A paralysed man in the US has become the first person to benefit from a brain chip that reads his mind.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. Recently four people, two of them partly paralysed wheelchair users, were able to move a computer cursor while wearing a cap with 64 electrodes that pick up brain waves.Mr Nagle's device, called BrainGate, consists of nearly 100 hair-thin electrodes implanted a millimetre deep into part of the motor cortex of his brain that controls movement.Wires feed the information from the electrodes into a computer which analyses the brain signals.The signals are interpreted and translated into cursor movements, offering the user an alternative way to control devices such as a computer with thought....To read more go to:
