monkeys, mind control

via Benedict Carey @ The New York Times Science section, i can't say it any better: "Monkeys Control a Robot Arm With Their Thoughts."

apparently, tiny implants @ the motor cortex guide the experimental monkeys as they manipulate a mechanical arm that brings them marshmallows and grapes. eventually, they adapt the arm's uses, going far beyond grab and move gestures, using the virtual appendage to push extra bits into their mouths and lick its fingers to get every delish morsel.

the technology could be used to aid humans suffering from brain and spinal cord injuries.
