Want clarity, surf the web

Internet access helps people maintain the ability to think sharply when we enter old age.

Health Day said the Semel Institute of Human Neuroscience and Behavior at the University of California (USA) recruited 24 volunteers aged 55-78 to perform a test. Among volunteers there are 12 people surfing the web daily, the remaining 12 people rarely do it. The researchers asked all volunteers to access the Internet, and electrodes were attached to their heads to monitor brain activity through magnetic resonance imaging.

After the resonance scan from the first time, the expert team instructed participants to find information in their own home for 14 consecutive days, exactly one hour a day. They then proceeded to perform a brain scan with a magnetic resonance imaging machine.

" We found that, in the first brain scan, the level of activity in the brain of volunteers using the Internet for many years was much stronger than that of the other group, " said Dr. Gary Small, professor of psychiatry at the University California, speaking.

But after surfing the web at home for two weeks, the level of brain activity of the little surfers increased very quickly and reached the level of the experienced group, Small said.

"This is evidence that, after a relatively short period of time, the intensity of brain activity can change when we do thoughtful tasks," said Dr. Richard Lipton, professor of psychiatry. Sutra and pathology of the University of California, said.

Professor Gary said that when searching for information online, people make a lot of decisions even though we are not aware of it. However, he warned that positive changes only appear if we surf the web properly.

" You can practice thinking skills through the Internet, but if you only go to the site to shop or gamble, no positive changes will happen, " the professor warned.
