Neurologist Vilayanur S. Ramachandran is known for his work in behavioral neurology and psychophysics. In this 2007 TED talk, he explores how brain damage can reveal about the connections between the internal structures of the brain and the mind. He talks about phantom limb pain, synesthesia (when people hear color or smell sounds), and the Capgras delusion. Ramachandran was the original inventor of the “Mirror Box” (but don’t click on the link, better watch the talk first!). Extraordinary talk.
