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.

Scientists Read Monkeys’ Inner Thoughts

By decoding brain activity, scientists were able to 'see' that 2 monkeys were planning to approach the same reaching task differently - even before they moved a muscle.

Thought Control of Prosthetic Limbs Funded by DARPA

Thought control of prosthetic limbs via brain-controlled interfaces will be tested and developed with funding from DARPA. Human subjects will test neural interface systems used to control prosthetic limbs.
