Monkeys in Nicolelis lab control both arms using brain activity

Duke’s Miguel Nicolelis continues to advance brain machine interface, and in his latest experiment, monkeys have learned to control the movement of both arms on an avatar using their brain activity.

The findings  advance efforts to develop bilateral movement in brain-controlled prosthetic devices for severely paralyzed patients.  Until now brain-machine interfaces could
only control a single prosthetic limb.
