Is Facebook changing our brains?

Scientists have found a direct link between the number of ''friends'' a person has on Facebook and the size of certain brain regions.

The more friends, the bigger the brain regions. The scientists say this raises the possibility that using online social networks might change our brains.

The four areas involved are known to play a role in memory, emotional responses and social interactions.

So far, however, scientists can't say whether having more Facebook connections makes particular parts of the brain larger or whether some people are simply predisposed or "hard wired" to have more friends.
