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.

Re "Head case puzzle," Opinion, July 15 Robert M. Sapolsky highlights the paradox between biological causes of abnormal behavior and the issue of assessing moral and legal responsibility. After 40-plus years in psychiatry, I have found that the most useful pathway is to accept the paradox, following John Stuart Mill's advice: While ultimately our will is not free, for the sake of an orderly society, it is necessary to act as if it were. Pragmatically, I interpret this to mean that when the biological causation is extraordinary (major brain damage or an acute cerebral infection)

"Brains on Trial," Thursday and Sept. 19 on PBS, offers a two-part look at "how brains work when they become entangled with the law. " That is not the John Agar 1950s sci-fi flick it might first sound like, but a look at how recent research into neuroscience and brain mapping changes our understanding of basic questions of human reliability, memory and bias among witnesses, juries and judges. These epistemological problems, pondered by philosophers since time immemorial, are no less difficult today; if anything, they are complicated by new knowledge.

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.

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.

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.

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.

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.
