This is one of those blow-your-mind TED talks. Jill Bolte Taylor, a brain researcher, had a stroke. But it wasn’t an ordinary stroke. Because of her training, and her insight into the way the brain works, she actually watched – calmly and with curiosity – as her brain functions shut down, one by one. Not only that, but she felt she attained a new level of consciousness beyond left brain/right brain – and said it was lovely. Totally fascinating.

How about you – have you seen any TED talks that you found fascinating? If so, I’d love to know. It’s great if they’re about medical stuff – but I’m interested to hear about non-medical ones too.
