This is an amazing TED talk by Neuroanatomist Jill Bolte Taylor. One morning, she realised she was having a massive stroke. Her observations of this process and how our brains work are really thought provoking. This talk made me think about how our brains work and define us, and how the brain connects us to each other. NB: she uses a real brain as a demonstration.
