Oliver Sacks - Musicophilia - Amnesia and Music
I just saw an awesome piece on Oliver Sax the neurologist, on dutch tv. It featured a man struck by lightning in a phone cell suddenly having musical composing ability, a man who grabbed his wife's head cause he mistook it for his hat, and the healing power of music, including alzheimers and amnesia. His book Awakenings about the 1930s Sleeping Sickness epidemic was turned into a movie and he was played by Robin Williams. Check out youtube for more, I can't find much video that's as good as what I saw earlier though.
