Split personalities

This fascinating short video give some insight into how our brain (or should I say brains?) work. The subject has had his 2 hemispheres severed in an attempt to decrease epileptic seizures. The video shows how Joe can now 'talk' to his disconnected right half of his brain through letting it draw pictures for him with his left hand. Amazing stuff, thanks for that to Donald Clark.

I am truly fascinated by research like this, in particular with the more philosophical questions that it raised about identity. Another amazing video on this topic is from Jill Taylor, in one of the most gripping TEDtalks I have seen. Jill describes how she one morning discovered she was having a massive stroke... Quite an opportunity for a brain scientist.
