2. Introductions
• Welcome and Introductions
• Soji Zen Center in Lansdowne
• Plan for the evening
• Presentation, instruction, practice, review
3. A little neuroscience
• States of consciousness – Meditation and
brain activity, EEG brain wave patterns –
What happens when we meditate ?

7. • Brain regions – Meditation and brain
activity, prefrontal lobe and parietal lobe
differences
• General observation that practice
weakens “reactive” pathways, increases
plasticity, flexibility.

10. Brain regions – long term structural
changes in brain tissue
11. Psychiatry Research Neuroimaging
• Mindfulness practice leads to increases in
regional brain gray matter density
M.R.I. brain scans taken before and after the
participants’ meditation regimen found increased
gray matter in the hippocampus, an area
important for learning and memory. The images
also showed a reduction of gray matter in the
amygdala, a region connected to anxiety and
stress. A control group that did not practice
meditation showed no such changes.
12. • "We found that brain regions associated
with attention and sensory processing
were thicker in meditators than in the non-
meditators," says Lazar. "Also, in one of
the regions, the differences in thickness
were most pronounced in older subjects,
suggesting that regular practise of
meditation might reduce normal age-
related thinning of the brain."

14. Other reported benefits
• More empathic
• Reduced emotional reaction to pain
• Greater patience
• Better focus and concentration
• Decrease in blood pressure and
reduced risk of coronary disease
• Reduction in addictive behaviors
15. What are some core elements of
Zen ‘philosophy’ and practice?
- Connectedness
- Mindfulness
- Seeing things clearly
- “Beginner’s Mind”
- Letting go of conditioned thinking
- Direct experience
16. • “The heart of Zen is the practice of zazen
— seated, silent meditation — which is
based predominantly on bringing your
attention to the present moment (often via
concentrating on your breath) and then
doing your best to keep it there. The
extension of that practice to life off the
cushion is fairly straightforward: When
you’re listening, really listen; when you’re
eating, just eat. Pay attention to what
you’re doing.”

Hippocampus
The hippocampus consists of two “horns” that curve back from the amygdala. It appears to be very important in converting things that are “in your mind” at the moment (in short-term memory) into things that you will remember for the long run (long-term memory). If the hippocampus is damaged, a person cannot build new memories, and lives instead in a strange world where everything they experience just fades away, even while older memories from the time before the damage are untouched! This very unfortunate situation is fairly accurately portrayed in the wonderful movie Memento, as well as in a more light-hearted movie, 50 First Dates. But there is nothing light-hearted about it: Most people who suffer from this kind of brain damage end up institutionalized.
Amygdala
The amygdalas are two almond-shaped masses of neurons on either side of the thalamus at the lower end of the hippocampus. When it is stimulated electrically, animals respond with aggression. And if the amygdala is removed, animals get very tame and no longer respond to things that would have caused rage before. But there is more to it than just anger: When removed, animals also become indifferent to stimuli that would have otherwise have caused fear and even sexual responses.
Zen training – increased grey matter in the hippocampus, reduction of gray matter in the amygdala. (Gray matter cell bodies of neurons. Resident brain tissue core.
