The National Football League's controversial injury legacy conjures images of powerfully built linebackers and fleet-footed running backs hobbled by years of brutal contact at the line of scrimmage. Few pause to consider the humbler kicker. Yet over the last six years, 64 former kickers and punters have filed claims for serious head or brain injuries against their former teams, according to a Los Angeles Times analysis of California workers' compensation data. The full article is found here . Among the filers is NFL Hall of Fame placekicker Jan Stenerud, who starred for the Kansas City Chiefs, Green Bay Packers and Minnesota Vikings, as well as all-pro performers like Morten Andersen and Norm Johnson.

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.

Does being bilingual give young children a mental edge, or does it delay their learning? It depends on who you ask. Bilingual education is regarded by some in education policy circles as little more than a half-baked technique of teaching students whose native language is not English. Though it takes many forms, bilingual education programs usually involve teaching students in both their native languages and in English. How much each language is used, and in which academic contexts, varies by program.

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.

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.

You can't sleep. You've tried counting sheep, drinking warm milk, maybe even taking medications like Benadryl or sleeping pills. Maybe next you should try cooling your brain. According to research presented Monday at Sleep 2011 , the annual meeting of the Associated Profession Sleep Societies, cooling the brain and can reduce the amount of time it takes people with insomnia to fall asleep -- and increase the length of time they stay that way. To achieve "frontal cerebral thermal transfer," as the cooling is called, researchers Dr. Eric Nofzinger and Dr. Daniel Buysse of the Sleep Neuroimaging Research Program at the University of Pittsburgh School of Medicine outfitted 24 people -- 12 with insomnia, and 12 without -- with soft plastic caps. The caps had tubes for circulating water at neutral, moderate or maximum "cooling intensity.

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.

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.

Let's get a couple of things straight first about estrogen, the so-called "female hormone. " First, it influences a lot more than just what's going on "down there": it's produced by the brain, of course, and brain scientists are increasingly studying estrogen as a "neuromodulator," a chemical with powerful effects on the brain as well as the reproductive system. Second, it's not just females who have estrogen, need it and suffer with its loss. Males do too, as a recent study involving the humble songbird makes clear.
