Researchers at the University of California Los Angeles studied people doing web searches while their brain activity was recorded with functional magnetic resonance imaging scans.

"What we saw was people who had internet experience used more of their brain during the search," said Dr. Gary Small, a UCLA expert on aging.

"This suggests that just searching on the internet may train the brain — that it may keep it active and healthy," said Dr Small, whose research appears in the American Journal of Geriatric Psychiatry.
