|ST. LOUIS - The teenager jukes missiles and blasts aliens in the video game. But it's his brain, not his thumbs, doing all the work. The 14-year-old, part of a study at Washington University, played the old-school video game "Space Invaders" by simply using his brain as a controller.|
Researchers hope the study ultimately leads to development of more advanced devices that use brain commands to control things such as artificial limbs and wheelchairs.
"My real motivation for this is helping people with disabilities," said Dr. Eric Leuthardt, an assistant professor of neurosurgery at the university's School of Medicine. "We chose to do a video game because we knew a teenage patient would be into it."
