Johnny Matheny of Port Richey, Florida, is learning to play the piano using a thought-controlled bionic arm. Matheny has undergone TMR surgery, performed by Dr. Albert Chi, to “reassign” nerves that once controlled an arm and hand he lost to cancer so that they could communicate with a robotic prosthetic.
