Monkeys Learn to Control Mechanical Arm Via Sensors Implanted in Brain

BENEDICT CAREY reports: Two monkeys with tiny sensors in their brains have learned to control a mechanical arm with just their thoughts, using it to reach for and grab food and even to adjust for the size and stickiness of morsels when necessary, scientists reported on Wednesday. The report, released online by the journal Nature
(i.e. Cortical Control of a Prosthetic Arm for Self-Feeding (Nature), is the most striking demonstration to date of brain-machine interface technology.
