Stanford tests brain-controlled prosthetic device

Jonathan Kao, Shenoy Lab

This video includes two clips. In the first, flashing targets on a virtual keypad are hit by monkeys (not shown) using their hands. The second clip also shows targets being hit. But this time, the motion is directed by an experimental device that taps into the monkey's brain. This device discerns their intention to hit the target and translates this thought into an electronic command that controls a virtual cursor. In the first clip the monkeys hit 10 targets in 9.9 second with their hands. It takes 11.4 seconds to hit 10 targets using the thought-control device.
