Researchers at the University of California in Los Angeles have discovered that Internet use is good for the brain and 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 affect performance.
It has long been thought that activities which keep the brain active, such as crossword puzzles, may help minimise that impact - and the latest study suggests that surfing the web can be added to the list.
Lead researcher Professor Gary Small said: "The study results are encouraging, that emerging computerised technologies may have physiological effects and potential benefits for middle-aged and older adults.
"Internet searching engages complicated brain activity, which may help exercise and improve brain function."
