Amputees can learn to control a robotic arm with their minds

Neuroscientists have shown how amputees can learn to control a robotic arm through electrodes implanted in the brain. The research details changes that take place in both sides of the brain used to control the amputated limb and the remaining, intact limb. The results show both areas can create new connections to learn how to control the device, even several years after an amputation.
