Keith Barry — Brain Magic

In this TED talk, Keith Barry shows us how our brains can fool our bodies — in a trick that works via podcast too. Then he involves the audience in some jaw-dropping (and even a bit dangerous) feats of brain magic.

Think of Keith Barry as a hacker of the human brain — writing routines that exploit its bugs and loopholes, and offering a revealing look at the software between our ears.

“I’m going to show you all how easy it is to manipulate the human mind once you know how.”
