Why People Use Facebook at Work

Ever wondered what our brain is doing while we take a break? During those quiet moments, our brain prepares to "see the world through a social lens", reveals a new study.

The findings explain why Facebook or Twitter are such popular diversions for people who feel like taking a break.

"The brain has a major system that seems predisposed to get us ready to be social in our spare moments. The social nature of our brain is biologically-based"

The research helped resolve a nearly 20-year-old mystery.

Neuroscientists have known since the 1990s that the brain includes a network of regions that seems to be most active during periods of rest.

During quiet moments, the brain is preparing to focus on the minds of other people - or to "see the world through a social lens".

The study was published in the Journal of Cognitive Neuroscience.
