Scientists are investigating, but have not yet figure out whether part of the brain responsible for social life that affects people who spend a lot of time on Facebook have more friends, or is used frequently, and social networks lead to changes in the brain.
By studying the brain's Facebook researchers found that people with a longer list of friends on this network have larger and denser structure in the three regions of the brain than those with only a few online friends.
It is the upper temporal lobe and the middle temporal gyrus, which are associated with social perception as the perception of another's look or facial expression, and entorinal cortex which in turn is associated with remembering faces and names.
- The question is whether the size of the "social" part of the brain encourages people to have more friends on Facebook or the area is subject to change due to frequent use of social networks - says lead researcher Geraint Rees, neurologist and professor at University College London, adding that it will be more studies are needed to reach the right answer.
