Also I'd like to share with you a fascinating TED talk by a neuroanatomist Jill Bolte Taylor, who
... had an opportunity few brain scientists would wish for: One morning, she realized she was having a massive stroke. As it happened -- as she felt her brain functions slip away one by one, speech, movement, understanding -- she studied and remembered every moment. This is a powerful story about how our brains define us and connect us to the world and to one another
Enjoy!
