Searching the internet could be good for your brain

Scientists from the University College of Los Angeles have found that for computer-savvy older adults, searching the internet triggers key centres in the brain that control decision-making and complex reasoning. The findings demonstrate that web search activity may help stimulate and possibly improve brain function.

As the brain ages, a number of structural and functional changes occur, including atrophy, reductions in cell activity, and increases in deposits of amyloid plaques and tau tangles, which can impact cognitive function.

Researchers noted that pursuing activities that keep the mind engaged may help preserve brain health and cognitive ability. Traditionally, these included games such as crossword puzzles, but with the advent of technology, scientists are beginning to assess the influence of computer use - including the internet.

For the study, the UCLA team worked with 24 neurologically normal research volunteers between the ages of 55 and 76. Half of the study participants had experience searching the internet, while the other half had no experience. Age, educational level, and gender were similar between the two groups.

Researchers found that during web searching, volunteers with prior experience registered a twofold increase in brain activation when compared with those with little internet experience.
