This undated photo made available from the Bio-Medical Campus University of Rome on Wednesday, Dec. 2, 2009 shows Pierpaolo Petruzziello's amputated hand linked with electrodes to a robotic hand, seen at top, as part of an experiment, called LifeHand, to control the prosthetic with his thoughts. A group of European scientists on Wednesday announced they successfully connected a robotic hand to a man, Petruzziello, who had lost an arm in a car accident, allowing him to control the prosthetic with his thoughts and feel sensations in the artificial limb. The experiment lasted a month. But scientists say it marks the first time an amputee has been able to make complex movements using his mind to control a biomechanic hand connected to his nervous system.
