Doctor Matthew, 63, has performed over 10,000 operations. He claims that head transplants would only be possible if the head was accompanied by the whole of its spinal cord. Advancements in nerve and spinal cord surgery, robotics and stem cell transplants mean it could be possible to attach an entire spinal cord and head to another body before 2030. Dr Matthew continued: "The thought of keeping the spinal cord in one piece has always been totally daunting, but now with modern technology you can do most things." Matthew also believes that consciousness would also move with the head and spinal cord from one body to another. The technology could treat spinal cord injuries and diseases like muscular dystrophy.
