If you've never read it, I love Oliver Sack's book "The Man who Mistook his Wife for a Hat": http://www.amazon.com/Man-Who-Mistook-His-Wife/dp/0684853949/ref=sr_1_3?ie=UTF8&s=books&qid=1277371133&sr=8-3 http://www.amazon.com/Man-Who-Mistook-His-Wife/dp/0684853949.... It's an amazing book full of stories just like in this article, about incredibly strange things that sometimes happen to people's brains. It's also the scariest book I've ever read: it made me realize, more than at any other time, just how much of who I am is determined by my physical body, which is incredibly easy to break. There are stories in there of people who can't understand the idea of "left" anymore. They can see out of their right eye, not their left. They can turn right, but not left. They can eat food off their plate, but only on the right side. Freaky as hell.
