Mind-controlled arm doesn't turn you into Dr. Octopus

We know that the brilliant but mad Dr. Octopus has a quartet of nigh indestructible appendages that he controls with his mind, but Otto Bock Healthcare from Europe have come up with something less menacing although extremely practical – a mind-controlled arm to help usher in a new era of prosthetics. This mind-controlled arm is the result of a four-year research project, where it has been successfully transplanted onto a young man known as Christian thanks to surgeons at the Vienna General Hospital. This arm will work in tandem with transplanted nerves that enable electrical impulses from the brain to reach the muscles in the chest. Such signals will be interpreted by a micro-computer that will then be used to control a prosthesis which will respond in real time to thoughts from one’s brain.
