NEWS: Patient's Thoughts Control Computer

London - A man has been able to control a computer by thought alone after
receiving an electronic implant that fused with his brain cells.

The American surgeons say it is the first time that such a connection has been
made directly in the brain, rather than with nerves in the spine or limbs.

"If you can run a computer, you can talk to the world", said Dr. Roy Bakay, of
Emory University in Atlanta, Georgia, whose team developed the implants.

He told a meeting of brain surgeons last week he had performed two of the
operations in which he persuaded the patients' brain cells to grow into his
implant, linking up with its electronics.

One of the patients, a 53-year old man known only as J.R., was almost totally
paralysed by a stroke. He is dependent on a ventilator and cannot speak,
although
he is fully alert and intelligent and knows everything that is going on around
him.

Once he received the implant he could control a cursor no a computer screen
and
point at different icons, triggering a computer voice to make comments such as
"I'm thirsty".

Now that J.R., who is in the Atlanta Veterans Affairs Medical Centre, can
select
phrases, his favourite is: "See you later. Nice talking with you."

The first volunteer, a woman suffering from a neuro-degenerative disease, was
given the implants 18 months ago and has since died.

The most immediate application of the technology would be for people who are
totally paralysed, enabling them to express their thoughts or even control
artificial limbs.
