The mind-to-movement system that allows a quadriplegic man to control a computer using only his thoughts is a scientific milestone. It was reached, in large part, through the brain gate system. This system has become a boon to the paralyzed. The Brain Gate System is based on Cyber kinetics platform technology to sense, transmit, analyze and apply the language of neurons. The principle of operation behind the Brain Gate System is that with intact brain function, brain signals are generated even though they are not sent to the arms, hands and legs. The signals are interpreted and translated into cursor movements, offering the user an alternate Brain Gate pathway to control a computer with thought, just as individuals who have the ability to move their hands use a mouse. Matthew Nagle,a 25-year-old Massachusetts man with a severe spinal cord injury, has been paralyzed from the neck down since 2001.After taking part in a clinical trial of this system, he has opened e-mail, switched TV channels, turned on lights. He even moved a robotic hand from his wheelchair.
