Researchers at Harvard have gotten to the bottom of why so many of us are compelled to share our every thought, movement, like and want through mediums like Twitter, Facebook, Foursquare, Instagram and Pinterest. In a series of experiments, the researchers found that the act of disclosing information about oneself activates the same sensation of pleasure in the brain that we get from eating food, getting money or having sex. It's all a matter of degrees of course, (talking about yourself isn't quite as pleasurable as sex for most of us)

A UC Irvine scientist has won a $165,000 grant to help develop a revolutionary technique for mapping brain activity, university officials announced. Ron Frostig, an assistant professor of psychobiology at UCI, received the award recently from the Arnold and Mabel Beckman Foundation. He plans to use the funds to continue research into the way various parts of the brain reflect light.

A group of scientists created a novel brain implant that improves cognitive performance and decision-making in a monkey. The device, developed in part by researchers at USC, manipulates ongoing brain activity to guide the animal away from mistakes and toward a correct decision. The study, published this week in the Journal of Neural Engineering, marks an important step toward implantable devices that could one day help people with brain injuries better perform basic tasks. The field of "brain prosthetics" has been dominated by efforts to restore physical abilities, like devices that use brain activity to move a robotic arm or a cursor across a screen.

Researchers have moved one step closer to understanding how anesthesia drugs work by identifying a component of brain activity that could explain why we lose consciousness under the influence of the drugs, according to a study published Monday in the Proceedings of the National Academy of Sciences. Though "going under" is an extremely common part of many medical procedures, the mechanism by which it works remains a mystery. This fact has practical ramifications: Some studies have shown that anesthesia can lead to loss of memory and other side effects, something researchers might be able to alleviate if they understand exactly what the drugs do in the body.

Does depth perception develop in humans as a result of nature or nurture? It's a question scientists have wondered about. And a new study comes to a surprising conclusion: Babies acquire binocular vision as a result of viewing the world around them, not merely thanks to genetic programming. "My guess was that it was going to be something in between nature and nurture," said study leader Ilona Kovacs, a psychologist at the Budapest University of Technology and Economics in Hungary.

Imprisoned financier Michele Sindona, who was once known as "God's Banker" because of his ties with the Vatican, was reported in a deep coma and near death, two days after being sentenced to a life term for ordering a murder. Sindona, 65, was taken ill as he ate breakfast at a prison in Voghera, Italy. He was reported to have been in a coma on arrival at a nearby hospital, where tests indicated no brain activity.

Could the teen brain identify chart-topping pop music hits -- and duds -- before a big-shot producer ever could? Perhaps, according to a study published online June 8 in the Journal of Consumer Psychology. Almost by accident, some previous research by Emory University scientists into the teen brain showed that adolescents' brain activity could potentially predict a song's ultimate success or failure. Back in 2006, Emory University neuroeconomist Gregory Berns had 27 teens between age 12 and 17 listen to 120 songs picked from Myspace that were relatively unknown artists without recording contracts, and measured the teens' brain activity.

How does the formidable human brain organize its memories? A new study used electrical activity of the brain to investigate. The resulting report shows that when people think of words that are linked by their meanings -- "apple" and "orange," for example -- the brain often exhibits similar patterns of activity. There's a futuristic, Big Brother-ish dimension to the work: The authors argue that down the road, their results might be useful in mind-reading approaches that rely on connecting measurements of brain activity to what a person is thinking.
