Controlling Monkey Brains and Behavior With Light

Researchers can control the behavior of monkeys by using pulses of blue light to very specifically activate particular brain cells. The findings represent a key advance for optogenetics, a state-of-the-art method for making causal connections between brain activity and behavior. Researchers say that similar light-based mind control could likely also be made to work in humans for therapeutic ends.
