Following on from yesterday, here is a link to the next part of the BBC report which contains some material on brain scans, brain activity and meditation. One of the most exciting recent discoveries in the field of neuroscience is that the brain is quite plastic all through life, and that we can change its activity patterns depending on what we do. So if we practice calmness, the brain changes in response to that, in the same way as it responds to the occasions when we “practice” worrying or being anxious.
