thought-controlled artificial arm
"Jesse Sullivan has two prosthetic arms, but he can climb a ladder at his house and roll on a fresh coat of paint. He's also good with a weed-whacker, bending his elbow and rotating his forearm to guide the machine.
He's even mastered a more sensitive maneuver -- hugging his grandchildren. (Watch Sullivan's bionic arm in action -- :41)
The motions are coordinated and smooth because his left arm is a bionic device controlled by his brain. He thinks, "Close hand," and electrical signals sent through surgically re-routed nerves make it happen.
Doctors describe Sullivan as the first amputee with a thought-controlled artificial arm."
