Contemplative Neuroscience II Emiliana Simon-Thomas How can we study the effects of meditation on the brain? 1. Compare the brains of people who are expert meditators to the brains of people who never meditated. 2. Teach people how to meditate and examine: a) Does meditation practice causes changes in the brain between before and after meditating? b) Are there differences in the brains of people that learn and practice meditation compared to people that learn and practice another skill? What can we measure? 1. Anatomical changes: cortical thickness, connectivity 2. Functional changes: activity during meditation, passive background activity, reactions to stimuli 3. Behavior (presumed to be produced by brain activation) during laboratory tasks a) b) c) d) Stimulus detection Cognitive performance Emotional experience Social factors: sharing, cooperation But how do we teach people, especially non-buddhists, how to meditate? Jon Kabat-Zinn, PhD, Massachusetts General Hospital Mindfulness Based Stress Reduction (MBSR) 100s of studies on MBSR have been done by many many scientists around the world Many have adapted MBSR to specific needs: • Mindfulness Based Cognitive Therapy • Mindfulness Based Childbirth and Parenting Education • Mindfulness Based Relapse Prevention • Mindful Awareness Practices (MAPS)… Neuroscientific study of Meditation Training: MBSR Jon Kabat-Zin (1982) Delivered MBSR to hospital patients with intractable chronic pain: 50% of people showed more than 50% reduction in pain. How? By uncoupling the sensory dimension of the pain experience from the affective/evaluative alarm reaction and reducing the experience of suffering. Neuroscientific study of Meditation Training: MBSR Kabat-Zinn & Davidson (2003) • Worked with 41 employees from a local technology company. • 25 employees did MBSR • 16 employees were on a “wait list” 8 weeks: MBSR or WAITING T1 T2 Neuroscientific study of Meditation Training: MBSR MBSR reduces trait anxiety Neuroscientific study of Meditation Training: MBSR MBSR increases left>right hemispheric assymetry Neuroscientific study of Meditation Training: MBSR MBSR increases immune response to flu vaccine Neuroscientific study of Meditation Training: MBSR Today, there are 1000s of published studies on MBSR, showing benefits in many different contexts for many different kinds of people. A possible underlying mechanism: Mindfulness increases willingness to tolerate uncomfortable emotions and sensations and emotional acceptance and decreases the impact and time needed to recover from negative emotional events. Neuroscientific study of Meditation Training: MBSR Hozel et. al. (2010) Harvard Medical School • Recruited 33 people • 16 did MBSR • 17 were on a “wait list” 8 weeks: MBSR or WAITING T1 T2 Neuroscientific study of Meditation Training: MBSR MBSR led to increased gray matter density in the hippocampus Neuroscientific study of Meditation Training: MBSR MBSR led to increased gray matter density in the temporal parietal junction and posterior cingulate. MBSR Cliff Saron, Ph.D., UC Davis The Shamatha Project Shamatha Meditation (1) mindfulness of breathing to induce relaxation of body and mind, and facilitate calming of compulsive thinking and sensory distraction (2) observing mental events (“settling the mind in its natural state”) to enhance attentional stability and vividness (3) observing the nature of consciousness (“awareness of awareness”) to increase the stability and vividness of attention (4) loving-kindness to arouse a heartfelt wish that self and others will experience genuine happiness and its causes, replacing resentment and hatred with a spirit of forgiveness; (5) compassion to arouse a heartfelt wish that self and others will be free of suffering and its causes, thereby overcoming apathy and aloof indifference (6) empathetic joy to arouse delight in one’s own and others’ successes, joys, and virtues, thus countering inclinations toward envy (7) equanimity to arouse an impartial, unconditional sense of affectionate concern for all beings, regardless of their closeness to or distance from oneself. Neuroscientific study of Meditation Training: Shamatha Shamatha study team (2005) • 30 people did a 3 month Shamatha meditation retreat at a remote mountain location guided by Alan Wallace (6-10 hrs/day) 3 months: Shamatha or WAITING T1 (+ measures during Shamatha) T2 Neuroscientific study of Meditation Training: Shamatha Neuroscientific study of Meditation Training: Shamatha Shamatha led to finer visual perceptual acuity Neuroscientific study of Meditation Training: Shamatha Shamatha was associated with longer Telomeres = healthier aging Neuroscientific study of Meditation Training: Shamatha Shamatha was associated with improved social emotional functioning Neuroscientific study of Meditation Training: Shamatha Shamatha was associated with changes in characteris tic brain oscillatory activity Cultivating Emotional Balance (CEB), UC San Francisco Neuroscientific study of Meditation Training: CEB Neuroscientific study of Meditation Training: CEB CEB team (2008) • Recruited 82 female school teachers 8 weeks: CEB T1 T2 CEB was associated with decreased negative emotions, healthier cardiovascular responses to stress, quicker recovery from stress and more pro-social behavior on tasks and in conversations. Barbara Fredrickson, University of North Carolina: Loving Kindness Meditation (LKM) Neuroscientific study of Meditation Training: LKM Fredrickson’s team • Recruited 67 people from a local computer company • 67 did LKM • 72 were on a “wait list” 8 weeks: LKM or WAITING T1 (+ measures during LKM training) T2 Neuroscientific study of Meditation Training: Loving Kindness People trained in Loving Kindness Meditation showed increased positive emotions, including: love, joy, gratitude, contentment, hope, pride, interest, amusement, and awe Richard Davidson, Ph.D., University of Wisconsin MBSR, Mindfulness & Compassion Training Neuroscientific study of Meditation Training: Compassion Training Davidson & Weng (2012) • Recruited 41 people – 21 did Compassion Training – 20 did Reappraisal Training 2 weeks: CT or RT T1 T2 Neuroscientific study of Meditation Training: Compassion Training Very brief, virtual compassion training led to greater connectivity between DLPFC and reward signaling regions, which predicted greater generosity. Tania Singer, Ph.D., Max Planck Institute, Germany Compassion/Loving Kindness Training Neuroscientific study of Meditation Training: Compassion Training Again, brief, compassion training led to greater activation of reward signaling regions, similar to that observed in an expert. Neuroscientific study of Meditation Training: Compassion Training Singer’s team (now) • 11 month contemplative training: attentional control, body and self-awareness, healthy emotion regulation, self-care, empathy, compassion and perspective taking in Leipzig, Germany. Emory – Tibet Partnership Cognitively Based Compassion Training (CBCT) Neuroscientific study of Meditation Training: CBCT Emory University Team (2010) • 45 participants did compassion training, 44 did “health class” 6 weeks: CBCT or Health T1 T2 Neuroscientific study of Meditation Training: CBCT Neuroscientific study of Meditation Training: CBCT CBCT led to lower ratings of negative mood after a social stress experience Neuroscientific study of Meditation Training: CBCT More CBCT practice predicted less stressrelated substances in the blood after a stress experience. Neuroscientific study of Meditation Training: CBCT More CBCT practice predicted less stressrelated substances in the blood. Neuroscientific study of Meditation Training: CBCT Neuroscientific study of Meditation Training: CBCT Emory, Harvard, University of Arizona Team (Now) • Compassion Attention Longitudinal Study Center for Compassion and Altruism Research and Education (CCARE), Stanford University: Compassion Cultivation Training (CCT) Neuroscientific study of Meditation Training: CCT Neuroscientific study of Meditation Training: CCT More CCT practice predicted less worry and less suppression of emotional experiences.
