This is 52 minute television program from Dan Rather that covers a wealth of information about the brain, its plasticity, its connections with meditation and other ways we can change our brain's functioning. The emphasis is on how the ways we use our brain in everyday situations actually changes the way our brain is wired.
I wrote about this in one of my earlier newsletters -- if you didn't get it and you're interested, let me know and I can sign you up for the newletters and their archives.
A bit of time commitment...but worth it for the overview on brain plasticity....
