Some amazing research on the brain

The doctor's statement that "I was absolutely stunned" says it all.

According to all the tests, the young woman was deep in a "vegetative state" -- completely unresponsive and unaware of her surroundings. But then a team of scientists decided to do an unprecedented experiment, employing sophisticated technology to try to peer behind the veil of her brain injury for any signs of conscious awareness.

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." . . .
