Note: What this is showing is that meditation actually makes physical changes to the brain. How amazing is that, but how logical. I wonder if these changes are handed down in some way to the children of meditators. Probably not, but if so would have tremendous ramifications on human evolution.
Meditation is known to alter resting brain patterns, suggesting long lasting brain changes, but a new study by researchers from Yale, Harvard, Massachusetts General Hospital, and the Massachusetts Institute of Technology shows meditation also is associated with increased cortical thickness.
