Exploring the neurobiology of politics, scientists have found that liberals tolerate ambiguity and conflict better than conservatives because of how their brains work. In a simple experiment reported todayin the journal Nature Neuroscience, scientists at New York University and UCLA show that political orientation is related to differences in how the brain processes information. Previous psychological studies have found that conservatives tend to be more structured and persistent in their judgments whereas liberals are more open to new experiences.

At the time of his death of an aortic aneurysm at age 76, Albert Einstein's brain was no bigger, and weighed no more, than the brain of an average older male. But beneath that unique organ's external folds and fissures, our universe was re-conceived. So not surprisingly, when photographs of Einstein's postmortem brain unexpectedly came to light recently, scientists were keen to find evidence of the genius that lay within. The result is a remarkably detailed look at the surface of Einstein's brain, published recently in the journal Brain.

Irritable bowel syndrome has been a tough disorder to understand. Studies have failed to show any structural problems in the gut that would account for the symptoms of pain, bloating, diarrhea and constipation. However, the disorder is real, affecting as many as 15% of Americans. A new study has found a possible connection between IBS and the brain. Researchers at McGill University and UCLA used MRI scans to reveal changes in the brains of women with the disorder. The researchers took MRI scans of 55 IBS patients and 48 healthy women for comparison.

In a major case of academic poaching involving crosstown rivals, USC has lured away two prominent neuroscientists from UCLA with a promise to expand their internationally renowned lab that uses brain imaging techniques to study Alzheimer's disease, schizophrenia, autism and other disorders. Arthur Toga and Paul Thompson will move to the USC Keck School of Medicine campus next fall, along with scores of graduate students, postdoctoral fellows and staffers who now work at UCLA's Laboratory of Neuro Imaging, known as LONI.

Scientists have discovered the fossilized brain of an animal that lived 520 million years ago. It is the oldest mostly intact nervous system to have ever been found. The incredible ancient brain and nervous system, described in the journal Nature, belongs to an Alacomenaeus , a member of the mega-claw family. These animals earned the name "mega-claw" ( megacheiran ), because they have two large scissor-like appendages that protrude from the top of their heads. Megacheirans lived in the early Cambrian-era ocean, swimming and scuttling around with nearly one dozen little legs, or swimmerettes.

Eating when you're not hungry--especially high-calorie, high-fat foods--may not always rise to the newly broadened clinical definition of an eating disorder. But the behavior that for many Americans is a routine pastime certainly contributes to excess weight gain, with its implications for health. And it is considered "disordered eating" by most mental health professionals. A study published Thursday in the journal Science adds to evidence that binge eating--and overeating generally--may have a biological basis.

Suppose you're under a lot of pressure. Does it feel like a huge flood is swirling around in your brain, tossing your thoughts every which way? Well, Ashley Merryman and Po Bronson say, maybe that's because your brain really is flooded - with dopamine. Dopamine is a neurotransmitter that the brain needs to run at full capacity, but as with so many good things, it's possible to have too much of it. So, as your brain keeps producing fresh dopamine, it has to keep getting rid of the old. In the prefrontal cortex, special enzymes called COMT - for catechol-O-methyltransferase - carry out these mop-up operations.

The Florida teen whose brain was impaled by a fishing spear survived because the spear, which entered his skull above the right eye and exited the back of his skull, missed the main blood vessels in his brain, news reports said Tuesday . Though one might not imagine the brain could take such abuse and survive - and the extent of recovery of 16-year-old Yasser Lopez is still to be determined - there are remarkable stories of those who...

Leave it to science to find a way to harsh the mellow of marijuana. A French research team has discovered a natural chemical brake that can tamp down the effects of THC, the main intoxicant in marijuana. They believe it could lead to ways to protect against memory loss, torpor and other side-effects better known as being stoned. “We have this built-in negative feedback mechanism, a brake” on cannabis intoxication, said University of Bordeaux neurobiologist Dr. Pier Vincenzo Piazza, principal author of a study published Thursday in the journal Science.
