A group of European scientists say they have successfully connected a robotic hand to a man who had lost an arm, allowing him to feel sensations in the artificial hand and control it with his thoughts.
The experiment lasted a month. Scientists say it was the first time an amputee has been able to make complex movements using his mind to control a biomechanical hand connected to his nervous system. The Italian-led team said at a news conference in Rome that last year they implanted electrodes into the arm of the patient, who had lost his left hand and forearm in a car accident.
The electrodes were removed after a month, during which the man learned to wiggle the robotic fingers and make other movements.
