Some amazing research on the brain
Without any hint that she might have a sense of what was happening, the researchers put the woman in a scanner that detects brain activity and told her that in a few minutes they would say the word "tennis," signaling her to imagine she was serving, volleying and chasing down balls. When they did, the neurologists were shocked to see her brain "light up" exactly as an uninjured person's would. It happened again and again. And the doctors got the same result when they repeatedly cued her to picture herself wandering, room to room, through her own home.
"I was absolutely stunned," said Adrian M. Owen, a British neurologist who led the team reporting the case in today's issue of the journal Science. "We had no idea whether she would understand our instructions. But this showed that she is aware." . . .
