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.

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.

If you know that a small seahorse-shaped structure deep in the brain -- the hippocampus -- is crucial to committing new facts and skills to memory, you have not only your hippocampus to thank; you also owe a debt of gratitude to Henry Gustav Molaison, known to brain scientists worldwide as the amnesic patient "H.M. " A new study shows that in death as in life, the man who lived 55 years virtually unable to form new memories deepened our understanding of what it takes to make them.

The tamping rod that blew through Phineas Gage's brain 163 years ago damaged only a small portion of his brain, but it disrupted a much larger proportion of his neural connections, UCLA researchers reported Wednesday. The finding, based on imaging of Gage's skull, may help explain the behavioral changes he endured following the accident. Phineas P. Gage was a construction supervisor for the Rutland and Burlington Railroad. On Sept. 13, 1848, he was working at a site near Cavendish, Vt. He had drilled a hole in a rock that was to be removed then filled the hole with blasting powder.

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.

In addition to claiming lives, marriages, homes and careers, alcoholism has a greedy way of robbing its victims of brainpower, as well. Over time, alcohol dependence literally shrinks the brain and several of its components. And in so doing, it erodes an alcoholic's ability to learn new tasks, remember things and organize for action. Even regular, heavy drinking can take a cognitive toll, researchers have found.

Leonardo da Vinci took them, as did Napoleon Bonaparte, Johannes Brahms and Winston Churchill. You could probably use one right now. Midday naps have long been touted as a good thing, lowering blood pressure and driving down the risk of heart attack. And if you snooze long enough, researchers have now found, they also permit your memory banks to do their filing, leaving your brain cleared and ready to learn in the latter half of the day. UC Berkeley psychology professor Matthew Walker and colleagues put 39 young adults through a demanding learning task and tested on it at noon.

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.

Memory researchers at the University of California Irvine are developing a large collection of remarkable research subjects, who themselves maintain a remarkably large collection of memories. They are people with "highly superior autobiographical memories," and UC Irvine researchers so far have found at least 22 -- and possibly as many as 32 subjects in this country alone -- who can remember with extraordinary accuracy and in extraordinary detail the events of their lives and the days on which they occurred.
