 Areas activated by reading a book in the brain of an experienced web user
|
For middle aged and older people at least, using the internet helps boost brain power, research suggests.
A University of California Los Angeles team found searching the web stimulates centres in the brain that control decision-making and complex reasoning.
The researchers say this might even help to counter-act the age-related physiological changes that cause the brain to slow down.
The study features in the American Journal of Geriatric Psychiatry.

A simple, everyday task like searching the web appears to enhance brain circuitry in older adults 
As the brain ages, a number of changes occur, including shrinkage and reductions in cell activity, which can impact on performance.
It has long been thought that activities which keep the brain active, such as crossword puzzles, may help minimise the impact - and the latest study suggests that surfing the web can be added to the list.
