Brain chip reads man's thoughts
Matthew Nagle, 25, was left paralysed from the neck down and confined to a wheelchair after a knife attack in 2001.
The pioneering surgery at New England Sinai Hospital, Massachusetts, last summer means he can now control everyday objects by thought alone.
The brain chip reads his mind and sends the thoughts to a computer to decipher. He can think his TV on and off, change channels and alter the volume thanks to the technology and software linked to devices in his home.
Scientists have been working for some time to devise a way to enable paralysed people to control devices with the brain.
Studies have shown that monkeys can control a computer with electrodes implanted into their brain.
