Scientists at University College London have detected a link between the number of friends one has on Facebook and the size of certain areas of the person´s brain.
Researchers say it is difficult to say whether people have so many friends on the social networking site because these brain areas are larger or the other way round.
"Some people are really consumed by it; maybe we understand this a little better -- this is really cool stuff," Dr. Richard Isaacson, professor at the University of Miami Miller School of Medicine, commented on the findings.
