Teenager Plays Space Invaders with His Mind.

A team of physicians and graduate engineering students on Monday helped 
a 14 year old boy suffering from epilepsy to become the first teenager 
to play a game with his mind.

Now, a St. Louis-area teenage boy and a computer game have gone 
hands-off, thanks to a unique experiment conducted by a team of 
neurosurgeons, neurologists, and engineers at Washington University in 
St. Louis.

he boy, a 14-year-old who suffers from epilepsy, is the first teenager 
to play a two-dimensional video game, Space Invaders, using only the 
signals from his brain to make movements.

The teenager had a grid atop his brain to record brain surface signals, 
a brain-machine interface technique that uses electrocorticographic 
(ECoG) activity - data taken invasively right from the brain surface. It 
is an alternative to a frequently used technique to study humans called 
electroencephalographic activity (EEG) - data taken non-invasively by 
electrodes outside the brain on the scalp. Engineers programmed the 
Atari software to interface with the brain-machine interface system.
