Double amputee controls bionic arms with his mind

Prosthetic technology has made huge leaps in recent years, but the Johns Hopkins University Applied Physics Laboratory is pushing it into Six Million Dollar Man territory
Scientists recently equipped double amputee Les Baugh with a pair of Modular Prosthetics Limbs (MPL) that he controls with his mind.
But it wasn’t easy for Baugh, a Colorado man who lost both arms in an electrical accident nearly 40 years ago. Surgeons at Johns Hopkins essentially had to wake up dead nerves, and reassign others in Baugh's chest, so he could control the arms through his nerves. The process of “re-enverating” was, as Baugh said in the video, quite painful.
