GOOGLING GOOD FOR GERIATRICS
Internet browsing has become a part of our life. There is different opinion about internet browsing. Some says that hours of sitting affect the health and eye sight. But the other says that browsing on internet keep their minds sharp. Please read this article and decide yourself
A TEAM of U.S. researchers has found searching the internet stimulates brain activity in the elderly and middle-aged and may help keep their minds sharp.
The study was carried out by scientists at the University of California at Ls Angeles (UCIA) and published in the latest edition of the American Journal of Geriatric Psychiatry. It said, the web triggers key centers in brain that control decision making and complex reasoning and may help stimulate and possibly improve brain function.
“The study results are encouraging, that emerging computerized technologies may have physiological effects and potential benefits for middle-aged and older adults” , said Dr Gary Small, the principal investigator of the study. ” Internet searching engages complicated brain activity, which may help exercise and improve brain function”. said Small, a professor at UCIA’s Semel Institute for Neuroscience and Human Behavior.
The study authors noted that their findings are the latest to suggest that complex activity that keeps the mind engaged, such as crossword puzzles, may help keep the brain healthy.
The UCIA researchers said they te4sted 24 neurologically normal research volunteers between the ages of 55 and 76, half with experience searching the internet and half with no experience.
The study participants performed web searches and book-reading tasks while undergoing functional magnetic resonance imaging (MRI) scans, which record brain-circuitry changes.
They all showed significant brain activity during book reading and web searching, but the internet-savvy group registered a twofold increase in brain activation during web use when compared with those with little internet experience.
They said the web-savvy group also registered greater activity in the frontal, temporal and cingulated areas of the brain, which control decision making and complex reasoning.
” Our most striking finding was that internet searching appears to engage a greater extent of neural circuitry that is not activated during reading…. but only in those with prior internet experience,” said Small.
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, he added.
