     Searching the Internet may help middle-aged and older adults keep their memories sharp, US researchers

said. 

     Researchers at the University of California, Los Angeles, studied people doing web searches by recording

their brain activity.

     "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, "This suggests that just searching on the Internet may train the

brain and that it may keep it active and healthy."

     "This is the first time anyone has simulated (模拟) 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. However, the two 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.

     "We found that in the book reading task, the visual cortex-the part of the brain that controls reading and

language-was activated," Small said, "In doing the Internet search task, there was much greater activity, but

only in the Internet-savvy (了解) group."

     He said it appears that people who are familiar with the Internet can engage in a much deeper level of brain

activity. Activities that keep the brain engaged can preserve brain health and thinking ability. Small thinks

learning to do Internet searches may be one of those activities.
