Workout for brain just a few clicks away

CHICAGO (Reuters) - Searching the Internet may help middle-aged and older adults keep their memories sharp, U.S. researchers said on Tuesday.
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," Dr. Gary Small, a UCLA expert on aging, said in a telephone interview.
"This suggests that just searching on the Internet may train the brain -- that it may keep it active and healthy," said Small, whose research appears in the American Journal of Geriatric Psychiatry.
Many studies have found that challenging mental activities such as puzzles can help preserve brain function, but few have looked at what role the Internet might play.
"This is the first time anyone has simulated an Internet search task while scanning the brain," Small said.
His team studied 24 normal volunteers between the ages of 55 and 76. Half were experienced at searching the Internet and the other half had no Web experience. Otherwise, the groups were similar in age, gender and education.
Both groups were asked to do Internet searches and book reading tasks while their brain activity was monitored. Continued...
