Sexual Arousal and Mindfulness are Linked in Complex Ways

 

By John M. de Castro, Ph.D.

 

“mindfulness meditation” training — which teaches how to bring one’s thoughts into the present moment — can quiet the mental chatter that prevents these women from fully feeling sexual stimuli.” – Gina Silverstein

 

Problems with sex are very common, but, with the exception of male erectile dysfunction, driven by the pharmaceutical industry, it is rarely discussed and there is little research. While research suggests that sexual dysfunction is common, it is a topic that many people are hesitant or embarrassed to discuss. Women suffer from sexual dysfunction more than men with 43% of women and 31% of men reporting some degree of difficulty. These problems have major impacts on people’s lives and deserve greater research attention.

 

Problems with sex with women can involve reduced sex drive, difficulty becoming aroused, vaginal dryness, lack of orgasm and decreased sexual satisfaction. Sexual function in women involves many different systems in the body, including physical, psychological and hormonal factors. So, although, female sexual dysfunction is often caused by physical/medical problems, it is also frequently due to psychological issues. This implies that it many cases female sexual problems may be treated with therapies that are effective in working with psychological problems.

 

Mindfulness trainings have been shown to improve a variety of psychological issues including emotion regulation, stress responses, trauma, fear and worry, anxiety, and depression, and self-esteem. Mindfulness training has also been found useful in treating sexual problems. But there is little empirical research. So, it makes sense to further investigate the relationship of mindfulness with female sexual arousal.

 

In today’s Research News article “Subjective and Oxytocinergic Responses to Mindfulness Are Associated With Subjective and Oxytocinergic Responses to Sexual Arousal.” (See summary below or view the full text of the study at: https://www.frontiersin.org/articles/10.3389/fpsyg.2019.01101/full?utm_source=F-AAE&utm_medium=EMLF&utm_campaign=MRK_999212_69_Psycho_20190528_arts_A), Dickinson and colleagues recruited women between the ages of 20 to 35 for a study on sexuality and stress hormones and measured them for mindfulness. They watched landscape photographs and rated their liking of the photographs and then provided salivary samples to assess oxytocin and cortisol. Oxytocin levels are a marker of sexual arousal. They then listened to 1.5-minute stories that were either neutral or erotic and provided salivary samples. They also rated their sexual arousal after each story. They then performed a breath focused meditation for 15 minutes and provided a third salivary sample. After a 15-minute quiet period they provided a fourth sample.

 

They found that the higher the women scored on mindfulness, particularly the describing facet, the higher their levels of reported arousal in response to the erotic stories. They also found that oxytocin levels did not significantly increase in response to the erotic stories, decreased significantly in response to mindful breathing, and increased during recovery. They further found that women high in the mindfulness facet of non-judging internal experience and women who were quicker in detecting mind wandering during meditation had significantly greater decreases in oxytocin during meditation. In addition, women who were quick in detecting mind wandering and women who reported large increases in sexual arousal while listening to the erotic stories had greater decreases in oxytocin while meditating.

 

These are complex results. They suggest that in women mindfulness, subjective sexual arousal, and endocrine markers of sexual arousal are all linked in complex ways. They also suggest that women who are high in mindfulness are more sexually responsive to erotic stimuli. This may suggest that mindfulness training may be effective in increasing women’s ability to be sexually aroused. Future research should investigate whether mindfulness training may be an effective treatment for women who have difficulty with sexual arousal.

 

“among women who have sexual difficulties, mindfulness not only improves their desire but improves their overall sexual satisfaction, too.” – Tracy Clark-Flory

Study Summary

 

Dickenson JA, Alley J and Diamond LM (2019) Subjective and Oxytocinergic Responses to Mindfulness Are Associated With Subjective and Oxytocinergic Responses to Sexual Arousal. Front. Psychol. 10:1101. doi: 10.3389/fpsyg.2019.01101

 

Mindfulness – the ability to pay attention, on purpose, without judgment, and in the present moment – has consistently been shown to enhance women’s sexual arousal. As a first step toward understanding potential neuroendocrine underpinnings of mindfulness and sexual arousal, we examined whether individual differences in subjective and neuroendocrine (i.e., oxytocin) responses to mindful breathing were associated with individual differences in subjective and neuroendocrine responses to sexual arousal. To achieve this aim, 61 lesbian, bisexual, and heterosexual women completed a questionnaire assessing dispositional mindfulness, underwent an arousal task while continuously rating their sexual arousal and a mindful breathing task, after which participants reported on their ability to detect attentional shifts, and provided salivary samples after each assessment. Results indicated that women who were quicker to detect attentional shifts and women who reported greater sexual arousability reported larger changes (decreases) in oxytocin in response to mindful breathing and were the only women to report increases in oxytocin in response to the sexual arousal induction. Results further indicated that individuals who report greater subjective responsiveness to mindfulness and sexual arousal appear to have an oxytocinergic system that is also more responsive to both arousal and to mindfulness. These results make a significant contribution to our understanding of the role of attentional processes in sexual arousal, and warrant future examination of oxytocin as a potential neuroendocrine mechanism underlying the link between mindfulness and sexual arousal.

Alter the Brain to Deal with Stress with Meditation and Yoga

Alter the Brain to Deal with Stress with Meditation and Yoga

 

By John M. de Castro, Ph.D.

 

“Brain researchers have detected improvements in cognition and emotional well-being associated with meditation and yoga, as well as differences in how meditation and prayer affect the brain.” – Michaela Jarvis

 

There has accumulated a large amount of research demonstrating that mindfulness has significant benefits for psychological, physical, and spiritual wellbeing. One way that mindfulness practices may produce these benefits is by altering the brain. The nervous system is a dynamic entity, constantly changing and adapting to the environment. It will change size, activity, and connectivity in response to experience. These changes in the brain are called neuroplasticity. Over the last decade neuroscience has been studying the effects of contemplative practices on the brain and has identified neuroplastic changes in widespread areas. In other words, mindfulness practice appears to mold and change the brain, producing psychological, physical, and spiritual benefits.

 

In today’s Research News article “Meditation and yoga practice are associated with smaller right amygdala volume: the Rotterdam study.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6302143/), Gotink and colleagues utilized the data on participants in the longitudinal Rotterdam Study who were 45 years of age and older  at the time of recruitment and at the time of measurement had a mean age of 64 years. They were interviewed to determine if the practiced meditation and yoga and whether these practices improved their coping with stress. They were also measured for body size, blood pressure, blood fat, diabetes, smoking, alcohol use, stress, anxiety, and depression. In addition, their brains were scanned with Magnetic Resonance Imaging (MRI).

 

They found that practitioners of meditation and yoga reported higher stress levels than non-practitioners, but reported that the practice helped them cope with the stress. In addition, meditation practitioners had higher depression levels than non-practitioners. It is possible that people who are under high levels of stress or are depressed tend to engage in meditation and yoga practices to help cope with it.

 

They also report that the practitioners had smaller volumes of the brain structures right side amygdala and left hippocampus. In addition, over a five-year period the practitioners had a significant decrease in amygdala volume. The amygdala is associated with negative emotions and its smaller volume may suggest fewer or weaker negative emotions in practitioners.

 

This was a cross-sectional study and causation cannot be determined. It is possible that people with certain types of brains are more likely to practice. It will require a randomized controlled trial to determine what effects yoga and meditation practice may have on the psychological state and nervous system volumes.

 

Alter the brain to deal with stress with meditation and yoga.

 

“Studies show that yoga increases relaxation in the brain, improves areas of the brain that help us manage pain, and protects us against age-related decline. Together, these benefits begin to reveal the scientifically validated effects of yoga practice on brain health.” – Angela Wilson

Abstract

To determine the association between meditation and yoga practice, experienced stress, and amygdala and hippocampal volume in a large population-based study. This study was embedded within the population-based Rotterdam Study and included 3742 participants for cross-sectional association. Participants filled out a questionnaire assessing meditation practice, yoga practice, and experienced stress, and underwent a magnetic resonance scan of the brain. 2397 participants underwent multiple brain scans, and were assessed for structural change over time. Amygdala and hippocampal volumes were regions of interest, as these are structures that may be affected by meditation. Multivariable linear regression analysis and mixed linear models were performed adjusted for age, sex, educational level, intracranial volume, cardiovascular risk, anxiety, depression and stress. 15.7% of individuals participated in at least one form of practice. Those who performed meditation and yoga practices reported significantly more stress (mean difference 0.2 on a 1–5 scale, p < .001) and more depressive symptoms (mean difference 1.03 on CESD, p = .015). Partaking in meditation and yoga practices was associated with a significantly lower right amygdala volume (β = − 31.8 mm3, p = .005), and lower left hippocampus volume (β = − 75.3 mm3, p = .025). Repeated measurements using linear mixed models showed a significant effect over time on the right amygdala of practicing meditation and yoga (β = − 24.4 mm3, SE 11.3, p = .031). Partaking in meditation and yoga practice is associated with more experienced stress while it also helps cope with stress, and is associated with smaller right amygdala volume.

Meditation Alter Short-Term and Long-Term Breathing

Meditation Alter Short-Term and Long-Term Breathing

 

By John M. de Castro, Ph.D.

 

“By activating the parasympathetic nervous system, meditation healthfully slows down heart rate, breathing rate, blood pressure, sweating, and soothing all other sympathetic nervous system fight or flight functions.” – EOC Institute

 

In our lives we are confronted with a variety of situations and environments. In order to successfully navigate these differing situations, we must be able to adapt and self-regulate. The Autonomic Nervous System (ANS) is designed to adapt physiologically to the varying demands on us. It is composed of 2 divisions; the sympathetic division underlies activation, including increases in respiration, heart rate, and blood pressure, while the parasympathetic division underlies relaxation, including decreases in respiration, heart rate, and blood pressure.

 

Mindfulness training has been shown through extensive research to be effective in improving physical and psychological health and particularly with the physical and psychological reactions to stress. These include alterations of the Autonomic Nervous System (ANS) producing physiological relaxation including reductions in breathing rates. But the effects of meditation on breathing has not been well studied.

 

In today’s Research News article “Breath Rate Variability: A Novel Measure to Study the Meditation Effects.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6329220/), Soni and colleagues recruited experienced meditators and nonmeditators who expressed interest in meditation. They were asked to close their eyes and sit quietly for 15 minutes. During which time they measured for heart rate and respiration.

 

They found that the meditators had significantly greater mean and median breathing time, standard deviation of the breath to breathe interval, standard deviation of the average breath to breathe interval, root mean square standard deviation of the average breath to breathe interval and significantly lower breath rate. These measures suggest that meditation practice produces short-term changes in breathing when at rest. In addition, heart rate and breath rate variability measures suggested that there was a significant increase in long-term parasympathetic input in the meditators.

 

These are complex but interesting results that suggest that meditation practice alters respiration over both the short and long term. On the short term, while at rest with eyes closed meditators have better, more relaxed, control of respiration. On the long term, meditator appear to have increased parasympathetic control of respiration. This suggest an overall relaxation of respiration. Meditation would appear to alter the overall balance in the autonomic nervous system toward increased parasympathetic (relaxation) control and decreases sympathetic (activation) control. This may explain some of the benefits of meditation for stress reduction.

 

So, relax short-term and long-term breathing with meditation

 

“all forms of meditation studied reduce physiological stress markers in one way or another, and therefore, all forms are likely beneficial in managing stress.” – Michaela Pascoe

Study Summary

 

Soni, R., & Muniyandi, M. (2019). Breath Rate Variability: A Novel Measure to Study the Meditation Effects. International journal of yoga, 12(1), 45–54. doi:10.4103/ijoy.IJOY_27_17

 

Abstract

Context:

Reliable quantitative measure of meditation is still elusive. Although electroencephalogram (EEG) and heart rate variability (HRV) are known as quantitative measures of meditation, effects of meditation on EEG and HRV may well take long time as these measures are involuntarily controlled. Effect of mediation on respiration is well known; however, quantitative measures of respiration during meditation have not been studied.

Aims:

Breath rate variability (BRV) as an alternate measure of meditation even over a short duration is proposed. The main objective of this study is to test the hypothesis that BRV is a simple measure that differentiates between meditators and nonmeditators.

Settings and Design:

This was a nonrandomized, controlled trial. Volunteers meditate in their natural habitat during signal acquisition.

Subjects and Methods:

We used Photo-Plythysmo-Gram (PPG) signal acquisition system from BIO-PAC and recorded video of chest and abdomen movement due to respiration during a short meditation (15 min) session for 12 individuals (all males) meditating in a relaxed sitting posture. Seven of the 12 individuals had substantial experience in meditation, while others are controls without any experience in meditation. Respiratory signal from PPG signal was derived and matched with that of the video respiratory signal. This derived respiratory signal is used for calculating BRV parameters in time, frequency, nonlinear, and time-frequency domain.

Statistical Analysis Used:

First, breath-to-breath interval (BBI) was calculated from the respiration signal, then time domain parameters such as standard deviation of BBI (SDBB), root mean square value of SDBB (RMSSD), and standard deviation of SDBB (SDSD) were calculated. We performed spectral analysis to calculate frequency domain parameters (power spectral density [PSD], power of each band, peak frequency of each band, and normalized frequency) using Burg, Welch, and Lomb–Scargle (LS) method. We calculated nonlinear parameters (sample entropy, approximate entropy, Poincare plot, and Renyi entropy). We calculated time frequency parameters (global PSD, low frequency-high frequency [LF-HF] ratio, and LF-HF power) by Burg LS and wavelet method.

Results:

The results show that the mediated individuals have high value of SDSD (+24%), SDBB (+29%), and RMSSD (+26%). Frequency domain analysis shows substantial increment in LFHF power (+73%) and LFHF ratio (+33%). Nonlinear parameters such as SD1 and SD2 were also more (>20%) for meditated persons.

Conclusions:

As compared to HRV, BRV can provide short-term effect on anatomic nervous system meditation, while HRV shows long-term effects. Improved autonomic function is one of the long-term effects of meditation in which an increase in parasympathetic activity and decrease in sympathetic dominance are observed. In future works, BRV could also be used for measuring stress.

Eye Movements Reveal Mind Wandering During Meditation

Eye Movements Reveal Mind Wandering During Meditation

 

By John M. de Castro, Ph.D.

 

“Distractions in the mind translate to micro movements in the eyes or eyelids, and vice-versa. Stillness of eyes brings stillness of mind, and vice-versa.” – Giovanni

 

We spend a tremendous amount of waking time with our minds wandering and not on the present environment or the task at hand. We daydream, plan for the future, review the past, ruminate on our failures, exalt in our successes. In fact, we spend almost half of our waking hours off task with our mind wandering. Mind wandering is also present even during meditation. Mind wandering interferes with our concentration on the present moment. Focused meditation, on the other hand, is the antithesis of mind wandering. Indeed, the more mindful we are the less the mind wanders.

 

A system of the brain known as the Default Mode Network (DMN) becomes active during wind wandering and relatively quiet during focused on task behavior. Meditation is known to reduce the size, connectivity, and activity of the Default Mode Network (DMN).  Hence, brain activity may help identify mind wandering when it occurs. Eye movements occur even when the eyes are closed and during meditation. They may also be indicators of mind wander in during meditation.

 

In today’s Research News article “Spontaneous eye movements during focused-attention mindfulness meditation.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6345481/), Matiz and colleagues recruited adult experienced meditators. They engaged in a 7-minute focused breath meditation or a 7-minute mind wandering where they were asked to “remember or imagine one or more events of their past or future in which they, or another person, were the protagonist.” During the session brain activity, the electroencephalogram (EEG), was recorded. They derived a measure from the EEG that indicated vertical and horizontal eye movements. They also measured the total amount of meditation experience for each participant.

 

They found that during the 7-minutes of mind wandering there were significantly more eye movements, including both vertical and horizontal movements, than during the7-minutes of  focused meditation. In addition, they found that the more meditation experience that the meditator had, the fewer the eye movements that were recorded under both conditions. Hence, experienced meditators not only move their eyes less during meditation and but also during mind wandering.

 

These are interesting findings that suggest that analysis of the brain’s electrical activity, electroencephalogram (EEG), may be able to detect when mind wandering is occurring during meditation. This could lead to the possibility of providing biofeedback to the meditator when the mind is wandering, lessening the amount of mind wandering and thereby deepening the meditative experience. This is an intriguing possibility for future research.

Abstract

Oculometric measures have been proven to be useful markers of mind-wandering during visual tasks such as reading. However, little is known about ocular activity during mindfulness meditation, a mental practice naturally involving mind-wandering episodes. In order to explore this issue, we extracted closed-eyes ocular movement measurements via a covert technique (EEG recordings) from expert meditators during two repetitions of a 7-minute mindfulness meditation session, focusing on the breath, and two repetitions of a 7-minute instructed mind-wandering task. Power spectral density was estimated on both the vertical and horizontal components of eye movements. The results show a significantly smaller average amplitude of eye movements in the delta band (1–4 Hz) during mindfulness meditation than instructed mind-wandering. Moreover, participants’ meditation expertise correlated significantly with this average amplitude during both tasks, with more experienced meditators generally moving their eyes less than less experienced meditators. These findings suggest the potential use of this measure to detect mind-wandering episodes during mindfulness meditation and to assess meditation performance.

Reduce Age-Related Decline in the Brain with Mindfulness

Reduce Age-Related Decline in the Brain with Mindfulness

 

By John M. de Castro, Ph.D.

 

“Long-term engagement in mindfulness meditation may enhance cognitive performance in older adults, and that with persistent practice, these benefits may be sustained. That’s great news for the millions of aging adults working to combat the negative effects of aging on the brain.” – B Grace Bullock

 

The aging process involves a systematic progressive decline in every system in the body, the brain included. This includes our mental abilities which decline with age including impairments in memory, attention, and problem-solving ability. It is inevitable and cannot be avoided. Using modern neuroimaging techniques, scientists have been able to view the changes that occur in the nervous system with aging. In addition, they have been able to investigate various techniques that might slow the process of neurodegeneration that accompanies normal aging. They’ve found that mindfulness practices reduce the deterioration of the brain that occurs with aging restraining the loss of neural tissue. Indeed, the brains of practitioners of meditation and yoga have been found to degenerate less with aging than non-practitioners.

 

In today’s Research News article “Default Mode Network, Meditation, and Age-Associated Brain Changes: What Can We Learn from the Impact of Mental Training on Well-Being as a Psychotherapeutic Approach?” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6466873/), Ramírez-Barrantes and colleagues review and summarize the research on the effects of meditation practice on brain function and aging focusing primarily on the Default Mode Network (DMN). It is composed of interconnected brain regions including the medial prefrontal cortex, posterior cingulate cortex, precuneus, inferior parietal lobule, and inferolateral temporal cortex. It is active when the mind is wandering and when the individual is involved in self-referential thinking.

 

Increased activation and functional connectivity of the Default Mode Network (DMN) are associated with the cognitive decline with aging. This makes sense as increased mind wandering would interfere with the attentional focus needed for high level thinking. Mindfulness practices such as meditation and yoga have been shown to both reduce the cognitive decline with aging and also to decrease the activation and functional connectivity of the DMN. This suggests that mindfulness practices may help prevent the cognitive decline in aging in part by reducing the activity of the DMN.

 

Ramírez-Barrantes and colleagues propose that age-related cognitive decline may be slowed or prevented by engaging in mindfulness practices that reduce the activity of the Default Mode Network (DMN). This would reduce mind wandering and improve attention focus resulting in a greater ability to engage in high level thinking. Much more research is needed to explore this interesting possibility.

 

So, reduce age-related decline in the brain with mindfulness.

 

“experienced meditators have higher concentrations of tissue in brain regions most depleted by aging. This suggests that meditation practice may help to minimize brain age and protect against age-related decline.” – Matt Caron

Abstract

Aging is a physiological process accompanied by cognitive decline, principally in memory and executive functions. Alterations in the connectivity of the default mode network (DMN) have been found to participate in cognitive decline, as well as in several neurocognitive disorders. The DMN has antisynchronic activity with attentional networks (task-positive networks (TPN)), which are critical to executive function and memory. Findings pointing to the regulation of the DMN via activation of TPN suggest that it can be used as a strategy for neuroprotection. Meditation is a noninvasive and nonpharmacological technique proven to increase meta-awareness, a cognitive ability which involves the control of both networks. In this review, we discuss the possibility of facilitating healthy aging through the regulation of networks through meditation. We propose that by practicing specific types of meditation, cognitive decline could be slowed, promoting a healthy lifestyle, which may enhance the quality of life for the elderly.

Change Brain Connectivity for Better Attention and Thinking with Mindfulness

Change Brain Connectivity for Better Attention and Thinking with Mindfulness

 

By John M. de Castro, Ph.D.

 

“mindfulness meditation training increases resting state connectivity between top-down executive control regions, highlighting an important mechanism through which it reduces stress levels.” – Daniel Reed

 

There has accumulated a large amount of research demonstrating that mindfulness has significant benefits for psychological, physical, and spiritual wellbeing. It even improves high level thinking known as executive function and emotion regulation and compassion. Its positive effects are so widespread that it is difficult to find any other treatment of any kind with such broad beneficial effects on everything from thinking to mood and happiness to severe mental and physical illnesses. This raises the question of how mindfulness training could produce such widespread and varied benefits. One possibility is that mindfulness practice results in beneficial changes in the nervous system.

 

The nervous system is a dynamic entity, constantly changing and adapting to the environment. It will change size, activity, and connectivity in response to experience. These changes in the brain are called neuroplasticity. Over the last decade neuroscience has been studying the effects of contemplative practices on the brain and has identified neuroplastic changes in widespread areas. In other words, mindfulness practice appears to mold and change the brain, producing psychological, physical, and spiritual benefits. The changes are complex and require sophisticated brain scanning techniques to detect. Hence there is a need to continue investigating the nature of these changes in the brain produced by meditation.

 

In today’s Research News article “Trait Mindfulness and Functional Connectivity in Cognitive and Attentional Resting State Networks.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6473082/), Parkinson and colleagues recruited undergraduate students who had never meditated, measured them for mindfulness, and scanned their brains under resting conditions with functional Magnetic Resonance Imaging (fMRI). They examined the functional connectivity of a number of established neural networks and their relationship with mindfulness.

 

They found that mindfulness was negatively related to the functional connectivity of the Default Mode Network (DMN) and positively related to the functional connectivity of the Salience Network, the Central Executive Network, and Attention Network. The Default Mode Network (DMN) has been shown to be associated with mind wandering and self-referential thinking. It is not surprising that mindfulness would be associated with lower levels of the functioning of this network. Indeed, previous work has demonstrated that mindfulness is associated with reduced “mind wandering.”

 

The Salience Network is involved in detecting and filtering important stimuli in the environment from the environment and thereby gets involved in a myriad of high level psychological and social functions. The results suggest that being more mindful is associated with being more sensitive to important information.

 

The Central Executive Network has been shown to be associated with high level thinking and behavioral control. Hence, the results further suggest that high mindfulness is associated with improved cognition. Indeed, mindfulness has been shown through extensive research to be associated with better cognitive ability.

 

Finally, the Attention Network has been found to be associated with, no surprise, the ability to attend and focus. This suggests that high mindfulness is associated with improved attention ability. Again, this reflects other research which demonstrated that mindfulness is associated with a greater ability to attend.

 

Hence the study demonstrated the associations with mindfulness with functional connectivity in various neural networks tracks the demonstrated effects of mindfulness on the individual’s ability to focus, think, and stay in the present moment. This further suggests that changes in the operations of the brain are produced by mindfulness and that hese changes in turn produced improved functional capacities.

 

So, change brain connectivity for better attention and thinking with mindfulness.

 

“Just 11 hours of learning a meditation technique induce positive structural changes in brain connectivity by boosting efficiency in a part of the brain that helps a person regulate behavior in accordance with their goals,” – University of Oregon

Abstract

Mindfulness has been described as an orienting of attention to the present moment, with openness and compassion. Individuals displaying high trait mindfulness exhibit this tendency as a more permanent personality attribute. Given the numerous physical and mental health benefits associated with mindfulness, there is a great interest in understanding the neural substrates of this trait. The purpose of the current research was to examine how individual differences in trait mindfulness associated with functional connectivity in five resting-state networks related to cognition and attention: the default mode network (DMN), the salience network (SN), the central executive network (CEN), and the dorsal and ventral attention networks (DAN and VAN). Twenty-eight undergraduate participants completed the Five-Facet Mindfulness Questionnaire (FFMQ), a self-report measure of trait mindfulness which also provides scores on five of its sub-categories (Observing, Describing, Acting with Awareness, Non-judging of Inner Experience, and Non-reactivity to Inner Experience). Participants then underwent a structural MRI scan and a 7-min resting state functional MRI scan. Resting-state data were analyzed using independent-component analyses. An analysis of covariance (ANCOVA) was performed to determine the relationship between each resting state network and each FFMQ score. These analyses indicated that: (1) trait mindfulness and its facets showed increased functional connectivity with neural regions related to attentional control, interoception, and executive function; and (2) trait mindfulness and its facets showed decreased functional connectivity with neural regions related to self-referential processing and mind wandering. These patterns of functional connectivity are consistent with some of the benefits of mindfulness—enhanced attention, self-regulation, and focus on present experience. This study provides support for the notion that non-judgmental attention to the present moment facilitates the integration of regions in neural networks that are related to cognition, attention, and sensation.

Change the Brain to Improve Resilience with Meditation

 

By John M. de Castro, Ph.D.

 

“Mindful people … can better cope with difficult thoughts and emotions without becoming overwhelmed or shutting down (emotionally). Pausing and observing the mind may (help us) resist getting drawn into wallowing in a setback.” – Badri Bajaj

 

Psychological well-being is sometimes thought of as a lack of mental illness. But it is more than just a lack of something. It is a positive set of characteristics that lead to happy, well-adjusted life. These include the ability to be aware of and accept one’s strengths and weaknesses, to have goals that give meaning to life, to truly believe that your potential capabilities are going to be realized, to have close and valuable relations with others, the ability to effectively manage life issues especially daily issues, and the ability to follow personal principles even when opposed to society. But stress can interfere with the individual’s ability to achieve these goals.  When highly stressed, resilience is required to cope with the stress and continue on the path to psychological well-being.

 

One way that mindfulness practices such as meditation may improve resilience is by altering the brain. The nervous system is a dynamic entity, constantly changing and adapting to the environment. It will change size, activity, and connectivity in response to experience. These changes in the brain are called neuroplasticity. Over the last decade neuroscience has been studying the effects of contemplative practices on the brain and has identified neuroplastic changes in widespread areas. In other words, mindfulness practice appears to mold and change the brain, producing psychological, physical, and spiritual benefits. The changes in the brain, however, that are responsible for increased resilience are unknown.

 

In today’s Research News article “The Immediate and Sustained Positive Effects of Meditation on Resilience Are Mediated by Changes in the Resting Brain.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6448020/), Kwak and colleagues recruited healthy adults to participate in a 4-day retreat. They were randomly assigned to a meditation retreat or a relaxation retreat. They were measured before and after the retreat and 3 months later for mindfulness, resilience, and religious preference. Also, before and after the retreat the participants underwent functional Magnetic Resonance Imaging (f-MRI) of their brains.

 

They found that in comparison to baseline and the relaxation retreat participants, the meditation retreat participants at the 3-month follow-up had significant increases in both mindfulness and resilience. They also found that the meditation group had significantly increased functional connectivity between the left rostral anterior cingulate cortex and the dorsomedial prefrontal cortex, precuneus, and angular gyrus. In addition, the greater the increase in the functional connectivity in the meditation retreat group the greater the increases in resilience and mindfulness. The increase in resilience was associated with the increase in mindfulness and this association was found to be partially mediated by the change in functional connectivity. In other words, increased mindfulness was associated with increased resilience directly and also indirectly by its association with the increased functional connectivity which was in turn associated with greater resilience.

 

The results are interesting and suggest that the effect of meditation on resilience is due to increases in mindfulness that change the brain to produce greater resilience. In particular, meditation appears to increase the functional connectivity between brain regions, the cingulate cortex and the prefrontal cortex and the precuneus, and angular gyrus, and thus is partially responsible for increased resilience.

 

Resilience is very important for the individual to be able to withstand the stress and negative events in life. Meditation appears to change the brain to help people better cope with the stresses of life. This may underlie, at least in part, the psychological and physical benefits of meditation practice.

 

So, change the brain to improve resilience with meditation.

 

“The emotional soup that follows a stressful event can whip up negative stories about yourself or others that goes on and on, beyond being useful. Mindfulness reduces this rumination and, if practiced regularly, changes your brain so that you’re more resilient to future stressful events.” – Shamash Alidina

Abstract

While recent studies have explored the maintenance of the effect of meditation on stress resilience, the underlying neural mechanisms have not yet been investigated. The present study conducted a highly controlled residential study of a 4-day meditation intervention to investigate the brain functional changes and long-term effects of meditation on mindfulness and resilience. Thirty participants in meditation practice and 17 participants in a relaxation retreat (control group) underwent magnetic resonance imaging scans at baseline and post-intervention and completed the Cognitive and Affective Mindfulness Scale (CAMS) and Resilience Quotient Test (RQT) at baseline, post-intervention, and the 3-month follow-up. All participants showed increased CAMS and RQT scores post-intervention, but only the meditation group sustained the enhancement after 3 months. Resting-state functional connectivity (rsFC) between the left rostral anterior cingulate cortex (rACC) and the dorsomedial prefrontal cortex (dmPFC), precuneus, and angular gyrus was significantly increased post-intervention in the meditation group compared with the relaxation group. The changes in rACC-dmPFC rsFC mediated the relationship between the changes in the CAMS and RQT scores and correlated with the changes in the RQT score both immediately and at 3 months post-intervention. Our findings suggest that increased rACC-dmPFC rsFC via meditation causes an immediate enhancement in resilience that is sustained. Since resilience is known to be associated with the preventative effect of various psychiatric disorders, the improvement in stress-related neural mechanisms may be beneficial to individuals at high clinical risk.

Become More Sensitive to Others with Meditation

 

By John M. de Castro, Ph.D.

 

“as we pay attention to our breath, our body, our lives, in this simple and gentle way, a natural consequence is the opening of the heart.” – Matthew Brensilver

 

Humans are social animals. This is a great asset for the species as the effort of the individual is amplified by cooperation. In primitive times, this cooperation was essential for survival. But in modern times it is also essential, not for survival but rather for making a living and for the happiness of the individual. This ability to cooperate is so essential to human flourishing that it is built deep into our DNA and is reflected in the structure of the human nervous system. This deep need for positive social interactions heightens the pain of social rejection.

 

Mindfulness has been found to increase prosocial behaviors such as altruism, compassion and empathy and reduce antisocial behaviors such as violence and aggression. In today’s Research News article “Exploring the Role of Meditation and Dispositional Mindfulness on Social Cognition Domains: A Controlled Study.” (See summary below or view the full text of the study at: https://www.frontiersin.org/articles/10.3389/fpsyg.2019.00809/full?utm_source=F-AAE&utm_medium=EMLF&utm_campaign=MRK_963174_69_Psycho_20190416_arts_A), Campos and colleagues examine the relationship of mindfulness to social cognition, “the mental operations that underlie social interactions, including perceiving, interpreting, and generating responses to the intentions, dispositions, and behaviors of others”.

 

They recruited a group of healthy adult meditation practitioners and a group of non-meditators and had them complete measures of mindfulness, empathy, emotion recognition, theory of mind, attribution style, depression, anxiety, and cognitive impairment. Comparing the two groups they found that the meditators had significantly higher levels of mindfulness, interpersonal reactivity (empathy), emotion recognition, and theory of mind and significantly lower levels of cognitive impairment and lower levels of attribution style, including hostility bias intentionality bias, blame, anger bias, and aggressivity bias. They also found that the higher the levels of mindfulness, particularly the non-reactivity facet of mindfulness, the higher the levels of empathy.

 

This study is cross-sectional and has to be interpreted with caution. The results, however suggest that meditators have higher levels of social cognition. That is, that meditators are much more sensitive to others. This, in turn, improves their ability to understand and interact with others. They also suggest that meditators have a better ability to be non-reactive to what is transpiring in the present moment. This would make them better at responding empathetically to others. Hence, the study suggests that meditation practice may improve the individual’s sensitivity to others.

 

So, become more sensitive to others with meditation.

 

“Learning to communicate with empathy can go a long way toward building more positivity in your relationships and reducing your stress. If we all focused more on listening and understanding each other, the world would be a lot less stressful—and a lot happier—place to live.” – Arthur Ciamamicoli

Campos D, Modrego-Alarcón M, López-del-Hoyo Y, González-Panzano M, Van Gordon W, Shonin E, Navarro-Gil M and García-Campayo J (2019) Exploring the Role of Meditation and Dispositional Mindfulness on Social Cognition Domains: A Controlled Study. Front. Psychol. 10:809. doi: 10.3389/fpsyg.2019.00809

 

Research suggests that mindfulness can induce changes in the social domain, such as enhancing emotional connection to others, prosocial behavior, and empathy. However, despite growing interest in mindfulness in social psychology, very little is known about the effects of mindfulness on social cognition. Consequently, the aim of this study was to explore the relationship between mindfulness and social cognition by comparing meditators with non-meditators on several social cognition measures. A total of 60 participants (meditators, n = 30; non-meditators, n = 30) were matched on sex, age, and ethnic group, and then asked to complete the following assessment measures: Mindful Awareness Attention Scale (MAAS), Five Facet Mindfulness Questionnaire Short Form (FFMQ-SF), Interpersonal Reactivity Index (IRI), Revised Eyes Test, Hinting Task, Ambiguous Intentions and Hostility Questionnaire (AIHQ), Hospital Anxiety and Depression Scale (HADS), and Screening for Cognitive Impairment in Psychiatry (SCIP). The results showed that meditators reported higher empathy (except for the personal distress subscale), higher emotional recognition, higher theory of mind (ToM), and lower hostile attributional style/bias. The findings also demonstrated that dispositional mindfulness (both total score assessed with MAAS and mindfulness facets using the FFMQ) was associated with social cognition, although it was not equally correlated with all social cognition outcomes, and correlation patterns differ when analyses were conducted separately for meditators and non-meditators. In addition, results showed potential predictors for each social cognition variable, highlighting non-reactivity to inner experience as a key component of mindfulness in order to explain social cognition performance. In summary, the findings indicated that the meditator sample performed better on certain qualities (i.e., empathy, emotional recognition, ToM, hostile attributional style/bias) in comparison to non-meditators and, furthermore, support the notion that mindfulness is related to social cognition, which may have implications for the design of mindfulness-based approaches for use in clinical and non-clinical settings.

Improve Feedback Learning with Focused Meditation

Improve Feedback Learning with Focused Meditation

 

By John M. de Castro, Ph.D.

 

“Meditation is a powerful tool for the body and the mind; it can reduce stress and improve immune function. But can it also help us train our minds to learn faster from feedback or information acquired through past experiences?” – Jasmine Collier

 

Learning is fundamental to humans’ ability to survive and adapt in our environments. It is particularly essential in modern environments. Indeed, modern humans need to spend decades learning the knowledge and skills that are needed to be productive. Essential to the learning process is reacting to feedback from the consequences of actions. This is known as the “Law of Effect. Mindfulness is known to improve learning. So, it would seem reasonable to investigate how mindfulness training may improve the ability to respond to the feedback and learn.

 

In today’s Research News article “Meditation experience predicts negative reinforcement learning and is associated with attenuated FRN amplitude.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6420441/), Knytl and Opitz recruited healthy adults and separated them into groups who were non-meditators, novice meditators, and experienced meditators. The meditators were practitioners of focused meditation. They performed a probablistic selection task while the electroencephalogram (EEG) was recorded. Event related potentials (ERPs) were recorded in response to the presentation of the symbols.

 

In the probablistic selection task the participants were asked to select between two symbols presented randomly on a computer screen. One symbol, if selected, would produce positive feedback (10 points). Whether that symbol produced the feedback did not occur on every occasion. There were different probabilities of feedback, 20%, 30%, 40%, 60%, 70%, 80%. In the 60% case feedback would occur 6 out of every 10 times the symbol was presented. The participants were not told which symbols would produce positive feedback. They had to discover it themselves.

 

They found that non-meditators were significantly more negatively biased while focused meditators were significantly more positively biased. The non-meditators were better at not responding on trials where there was no positive feedback symbol present while the focused meditators were better at responding on trials where there was a positive feedback symbol present. In addition, they found that the more years of focused meditation experience the larger the difference.

 

In the EEG, the focused meditators had the smallest feedback related negativity (FRN) which involves a greater negative going electrical response of the frontal lobes in the event related potential (ERP) that occurred about a quarter of a second after the stimulus on positive trials than on negative trials. This response is thought to signal reinforcement occurring in the brain systems. In addition, they found that the more years of meditation experience the larger the reduction in the FRN.

 

The study is complicated and the results difficult to interpret, but they suggest that focused meditation experience makes and individual more sensitive to positive reinforcement and less sensitive to negative reinforcement. This bias is reflected in both the behavioral and event related potential data. This suggests that the demonstrated ability of focused meditation training to improve attention ability improves the ability of the meditator to detect stimuli that produce positive reinforcement. This makes meditators better at learning the feedback signals provided by the environment.

 

So, improve feedback learning with focused meditation.

 

“Humans have been meditating for over 2000 years, but the neural mechanisms of this practice are still relatively unknown. These findings demonstrate that, on a deep level, meditators respond to feedback in a more even-handed way than non-meditators, which may help to explain some of the psychological benefits they experience from the practice.” – Paul Knytl

Abstract

Focused attention meditation (FAM) practices are cognitive control exercises where meditators learn to maintain focus and attention in the face of distracting stimuli. Previous studies have shown that FAM is both activating and causing plastic changes to the mesolimbic dopamine system and some of its target structures, particularly the anterior cingulate cortex (ACC) and striatum. Feedback-based learning also depends on these systems and is known to be modulated by tonic dopamine levels. Capitalizing on previous findings that FAM practices seem to cause dopamine release, the present study shows that FAM experience predicts learning from negative feedback on a probabilistic selection task. Furthermore, meditators exhibited attenuated feedback-related negativity (FRN) as compared with nonmeditators and this effect scales with meditation experience. Given that reinforcement learning and FRN are modulated by dopamine levels, a possible explanation for our findings is that FAM practice causes persistent increases in tonic dopamine levels which scale with amount of practice, thus altering feedback processing.

Improve Psychological Adjustment with Meditation

Improve Psychological Adjustment with Meditation

By John M. de Castro, Ph.D.

 

“Fine-tuning which type of mindfulness or meditation someone uses as a prescriptive to treat a specific need will most likely be the next big advance in the public health revolution of mindfulness and meditation.” – Christopher Bergland

 

Meditation training has been shown to improve health and well-being. It has also been found to be effective for a large array of medical and psychiatric conditions, either stand-alone or in combination with more traditional therapies. As a result, meditation training has been called the third wave of therapies. One problem with understanding meditation effects is that there are, a wide variety of meditation techniques and it is not known which work best for improving different conditions.

 

In focused attention meditation, the individual practices paying attention to a single meditation object, learns to filter out distracting stimuli, including thoughts, and learns to stay focused on the present moment, filtering out thoughts centered around the past or future. In open monitoring meditation, the individual opens up awareness to everything that’s being experienced regardless of its origin. These include bodily sensations, external stimuli, and even thoughts. The meditator just observes these thoughts and lets them arise and fall away without paying them any further attention. Loving Kindness Meditation is designed to develop kindness and compassion to oneself and others. The individual systematically pictures different individuals from self, to close friends, to enemies and wishes them happiness, well-being, safety, peace, and ease of well-being.

 

These techniques have common properties of restful attention on the present moment. They are also similar to many religious and spiritual practices. There are large differences between these practices that are likely to produce different effects on the practitioner. But what those differences are is not known. In today’s Research News article “Religiosity and Meditation Practice: Exploring Their Explanatory Power on Psychological Adjustment.” (See summary below or view the full text of the study at: https://www.frontiersin.org/articles/10.3389/fpsyg.2019.00630/full?utm_source=F-AAE&utm_medium=EMLF&utm_campaign=MRK_951898_69_Psycho_20190404_arts_A), Montero-Marin and colleagues explore the different effects of these practices on the psychological well-being of practitioners.

 

They recruited adult participants online and had them complete measures of happiness, depression, positive and negative emotions, and negative psychological adjustment. They were also asked to indicate the amount of prayer, and the types and amounts of meditation practices engaged in, including open monitoring, focused, and compassion meditation types.

 

They found that positive psychological states were associated with the amount of the various meditation practices and not particularly with religiosity or prayer. They found that the amount of focused meditation practice was significantly related to all measures of psychological adjustment, including happiness, depression, positive and negative emotions, and negative psychological adjustment. On the other hand, open monitoring practice was significantly associated with self-regulation of negative emotions and compassion meditation was significantly related to positive emotions and happiness.

 

These are interesting results that are cross-sectional and correlative. So, care must be taken in concluding causation. Nevertheless, the results suggest that meditation practice has positive benefits for the psychological state of the practitioner that are superior to religious practices. It appears that focused meditation practice has the greatest benefits while compassion meditation may help increase happiness and open monitoring meditation may help with dealing with negative emotions. Previous research has indicated some additional benefits of religiosity, prayer, and focused, open monitoring, and compassion meditation techniques. It remains for future research to better clarify the advantages and disadvantages of each of these meditation types.

 

So, improve psychological adjustment with meditation.

 

”For someone who meditates, the practice offers a chance to improve physical wellbeing, as well as emotional health. However, there is no “right way” to meditate, meaning people can explore the different types until they find one that works for them.” – Zawn Villines

There has been increased interest in the relationships between religiosity, meditation practice and well-being, but there is lack of understanding as to how specific religious components and distinct meditation practices could influence different positive and negative psychological adjustment outcomes. The aim of this study was to assess the explanatory power of religious beliefs and the practice of prayer, focused attention (FA), open monitoring (OM), and compassion meditation (CM) on psychological adjustment, taking into consideration a number of practice-related variables such as session length, frequency of practice and lifetime practice. Psychological adjustment was assessed by means of happiness, positive affect, depression, negative affect, and emotional overproduction. A cross-sectional design was used, with a final sample comprising 210 Spanish participants who completed an online assessment protocol. Hierarchical regressions were performed, including age, sex and psychotropic medication use in the first step as possible confounders, with the addition of religious beliefs and the practice of prayer, FA, OM, and CM in the second step. FA session length was related to all psychological adjustment outcomes: happiness (ΔR2 = 0.09, p = 0.002; β = 0.25, p = 0.001), positive affect (ΔR2 = 0.09, p = 0.002; β = 0.18, p = 0.014), depression (ΔR2 = 0.07, p = 0.004; β = -0.27, p < 0.001), negative affect (ΔR2 = 0.08, p = 0.007; β = -0.27, p < 0.001) and emotional overproduction (ΔR2 = 0.07, p = 0.013; β = -0.23, p = 0.001). CM session length was related to positive affect (β = 0.18, p = 0.011). CM practice frequency was associated with happiness (ΔR2 = 0.06, p = 0.038; β = 0.16, p = 0.041). Lifetime practice of FA was related to happiness (ΔR2 = 0.08, p = 0.007; β = 0.21, p = 0.030) and OM to emotional overproduction (ΔR2 = 0.08, p = 0.037; β = -0.19, p = 0.047). Religious beliefs and prayer seemed to be less relevant than meditation practices such as FA, OM, and CM in explaining psychological adjustment. The distinct meditation practices might be differentially related to distinct psychological adjustment outcomes through different practice-related variables. However, research into other forms of institutional religiosity integrating social aspects of religion is required.
