...series of elegant experiments, Smith and her collaborators showed that this temporary learning deficit could be traced to a remarkable change that occurs at puberty in the hippocampus, a region of the brain that is involved in remembering places and integrating other kinds of learning. The change affects the GABA neurotransmitter system. GABA, which is present in all mammals, inhibits or down-regulates nerve signals, as opposed to exciting them; this calming, relaxing system is activated by tranquilizers like Valium and the popular sleep drug Ambien, which attach to GABA receptors and act similarly to GABA. But at puberty, female...
Smith and company found that having this abundance of receptors, which recede later in adolescence, interferes with learning. And just as fascinating, a dose of THP reverses the learning deficit. "We are suggesting that mild stress is advantageous to learning in adolescence," she says. (Smith's current study involved only female mice; she plans to look next at males and females to see if there are gender differences on the learning task...
...Seattle, Myers is heading up the NIMH study that is specifically designed to determine whether expert psychiatric care through telemental health is more effective than treatment in a typical primary-care setting for children ages 6 to 12 who have attention-deficit/hyperactivity disorder...
...which make up 2% of the state budget, have thus joined the slash-and-cut regimen that has befallen school districts, cities, and social services across California as the state deals with a $21 billion shortfall this year. (That comes on the heels of last year's $40 billion deficit.) (See how California's crisis has hit its prized universities...
...this costs money, and with a federal-budget deficit of more than 6% forecast for this year, Russia does not have a lot to spare. Prime Minister Vladimir Putin has pledged an initial outlay of $12 billion from the budget to fund the construction projects, but that is not expected to be enough - and private investors have indicated that they may not be willing to make up the difference during the economic downturn. There are also signs that the initial cost estimates have been way off. Last July, the government said the total construction bill would run about $6.6 billion...
