Using Internet may improve your brain functions
Using the internet for just a few days alters our brains – and may help improve cognitive function in the elderly, according to new research.
Senior research associate Teena D. Moody, one of the authors of the study, said: "The results suggest that searching online may be a simple form of brain exercise that might be employed to enhance cognition in older adults."

The research, performed by psychiatrists and neuroscientists at the University of California, Los Angeles (UCLA), looked at the brain circuitry of adults between the ages of 55 and 78 who had rarely used the internet, compared with those who used it daily.
They then had the volunteers perform web searches while undergoing brain scans called functional magnetic resonance imaging or fMRI, which recorded the changes in brain activity.
After that, the test subjects went home, and were asked to use the internet for an hour a day, using web searches to answer questions on a variety of topics by reading different websites.
A week later they returned to the lab and were scanned again as they carried out a different set of internet searches. The brains of the regular internet users already showed activity in these regions, and researchers were startled to note that it only took a few days for inexperienced users to catch up.
As the trial was small – just 24 people – more research is needed to confirm the results. Also, further studies to establish the effects on younger brains, as well as to determine what sort of web use has the greatest cognitive effects, are also needed.
