A light switch for neurons Ed Boyden on TED.com

Ed Boyden shows how, by inserting genes for light-sensitive proteins into brain cells, he can selectively activate or de-activate specific neurons with fiber-optic implants. With this unprecedented level of control, he’s managed to cure mice of analogs of PTSD and certain forms of blindness. On the horizon: neural prosthetics. (Recorded at TED2011, March 2011, in Long Beach, CA. Duration: 18:24)
