Teenager moves video icons by imagination A U.S. boy has become the first teenager to play a two-dimensional video game using only the signals from his brain to make movements. Washington University researchers say the unidentified 14-year-old St. Louis boy's achievement might lead to creation of biomedical devices that can control artificial limbs, enabling the movement of a prosthesis by just thinking about it. Researchers placed a grid on the boy's brain to record brain surface signals -- an interface technique that uses electrocorticographic activity. Engineers programmed the video game -- Space Invaders -- to interface with the brain-machine interface system... The study was led by Dr. Eric Leuthardt, assistant professor of neurological surgery, and Daniel Moran, assistant professor of biomedical engineering...
