Facebook and Twitter trigger the same sensation in the brain as food or money

Get someone talking about themselves and you'll have a friend forever. I've heard this so many times but now Harvard University Professors have released a study explaining way. Talking about ourselves triggers pleasure points in your brain, much like food.

Talking about ourselves—whether in a personal conversation or through social media sites like Facebook and Twitter—triggers the same sensation of pleasure in the brain as food or money, researchers reported Monday.

About 40% of everyday speech is devoted to telling others about what we feel or think. Now, through five brain imaging and behavioral experiments, Harvard University neuroscientists have uncovered the reason: It feels so rewarding, at the level of brain cells and synapses, that we can't help sharing our thoughts.

One experiment asked the volunteers questions about themselves and about other people.  They offered financial incentives if the volunteers answered questions about other people – but between 17% and 25% of the time, they chose to give up the money and answer questions about themselves instead.

"It rings true to me," said psychologist James Pennebaker at the University of Texas at Austin... We love it if other people listen to us. Why else would you tweet?"

Humans are wired to Tweet, it's in our very nature to share stories about ourselves. So if you think Twitter is a little narcissistic you'd be right....just like we are offline too.
