Brain implant controls robotic arm - with the power of thought

Breakthrough as neuro-prosthetic device implanted in "higher" brain region, allows paralysed man to control robotic arm just by thinking about it

Erik Sorto, a 34-year old American, has been unable to move his arms or legs for more than a decade, since a gunshot wound left him paralysed from the neck down. Even now, he misses the little things.

"I want to be able to drink my own beer - to be able to take a drink at my own pace, when I want to take a sip out of my beer and to not have to ask somebody to give it to me," he said. "I really miss that independence."
