Military Funds Brain-Computer Interfaces to Control Feelings

A $70 million program will try to develop brain implants able to regulate emotions in the mentally ill.

Researcher Jose Carmena has worked for years training macaque monkeys to move computer cursors and robotic limbs with their minds. He does so by implanting electrodes into their brains to monitor neural activity. Now, as part of a sweeping $70 million program funded by the U.S. military, Carmena has a new goal: to use brain implants to read, and then control, the emotions of mentally ill people.
