A robotic hand that can be controlled with thoughts has been fitted onto a man, who had lost an arm.
The feat achieved by a group of European scientists required a month of experimentation, reports the Daily Telegraph.
The Italian-led team said that it was the first time an amputee could make complex movements using his mind to control a biomechanic hand connected to his nervous system.
At a news conference on Wednesday in Rome, the researchers said 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.
