With all of the complex brain science findings out there, I really enjoyed this TED talk from neuroscientist Daniel Wolpert that goes back to one of the most fundamental questions about brains: why do we have them at all? Wolpert argues that the only reason we evolved our brains is because we had to move, not because we had to think or feel. This is a fun and thought-provoking talk that may get you thinking about your brain in a markedly different way! Incidentally, Wolpert is a compelling and humorous speaker, too.
