(Ivanhoe Newswire) -- People who spend time surfing the web may be building brain power at the same time.
A new study from the University of California, Los Angeles reveals middle-aged and older adults who use the Internet may trigger centers in their brain responsible for decision-making and reasoning.

Researchers performed a functional magnetic resonance imaging (fMRI) scan as experienced and non-experienced participants searched the Web and performed book-reading tasks. Both exercises activated the brain in both groups, but there were some major differences. Web-savvy participants who searched the Web activated areas in their brain responsible for decision-making and reasoning. They also showed twice the amount of brain activity than those with little Internet experience.
Compared with simple reading, the Internet's abundance of choices forces people to make decisions about what to click to find out more information. "A simple, everyday task like searching the Web appears to enhance brain circuitry in older adults, demonstrating that our brains are sensitive and can continue to learn as we grow older," Gary Small, M.D., principal investigator and a professor at the Semel Institute for Neuroscience and Human Behavior at UCLA, was quoted as saying.
Researchers say you may want to add surfing the web to the list of other brain teasers, such as crossword puzzles and Sudoku. "Internet searching engages complicated brain activity, which may help exercise and improve brain function," Dr. Small explained. "The study results are encouraging that emerging computerized technologies may have physiological effects and potential benefits for middle-aged and older adults."
