The new work reveals how gluelike protein co...

Robotic joystick reveals how brain controls movement

By training a group of human subjects to operate a robot-controlled joystick, Johns Hopkins researchers have shown that the slower the brain "learns" to control certain muscle movements, the more likely it is to remember the lesson over the long haul. The results, the investigators say, could alter...
