Dr. Jay Meythaler, specialist and chief for physical medicine and rehabilitation at Wayne State\'s Medical School and the Detroit Medical Center, commented about new technology which gives a paralyzed man the ability to perform such tasks as opening e-mail, turning on the television and controlling a robotic arm by using his thoughts. These tasks were made possible through a procedure of implanting electrodes into the patient\'s brain which generate electrical signals. Meythaler called the research landmark adding that the technology is hugely relevant, not only in helping people with spinal cord injuries, but also in improving prosthetic devices for amputees.
