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?

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.

Kabat-Zinn & Davidson (2003)
• Worked with 41 employees from a local technology
company.
• 25 employees did MBSR
• 16 employees were on a “wait list”

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.

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.
