...Right. It's so counterintuitive. Play builds brains and gives children the ability to impose self-control and creates within brain circuitry the ability to pay attention. When you look at kids playing, adults see it as a waste of time. They have no clue what play does. Vigorous social play stimulates the growth of brain cells in the executive portion of the brain in the frontal cortex, and that lays the foundation for the circuitry of self-regulation, which is what you need to pay attention when you're at school. I'll just give you a very, very...
...accepted as an article of faith in the prevention community that "the teen brain" should not be exposed to any alcohol. But the research on alcohol and the young brain is actually quite murky. It has mainly shown that very high doses of alcohol given to adolescent rats (those roughly 40 days old) affect those animals differently from the way alcohol affects adult rats. In typical studies, the rats are injected with 5 g of alcohol per 1,000 g of their body weight, often after the rodents have been deprived of food for 12 hours. Rats metabolize alcohol about...
What these rat studies tell us is that exposure to very large amounts of alcohol (particularly repeated exposure) probably inhibits normal brain development. And yet there are signs that in certain ways the adolescent brain is better equipped to handle alcohol than the adult brain. Adolescent rats show less vulnerability than adult rats to alcohol's sedating effects (which is one reason kids can party so much longer than adults). Other studies have found that, as White writes, "adolescents may be less sensitive than adults to the effects of alcohol on motor coordination." None of this means you should...
...rather than architects of their own, have made comic-book creators Hollywood's latest big-budget auteurs. Because they work with such low overhead compared with moviemakers, comic writers and artists can take many more creative chances than directors. "You don't have endless development meetings that turn your brain into milk," says Miller. "You get to at least see what an individual has to offer." After co-directing Sin City with Robert Rodriguez in 2005, Miller is completing his comics-to-movies arc by directing The Spirit, an adaptation of a 1940s crime-fighting strip, for a December release...
...Vilain, who studies the genetic factors behind sexuality and sexual orientation, notes that it may turn out that the brains of gay men possess only some 'feminized' structures, while retaining some masculine ones, and this is reflected in how they act on their sexuality. "We know from studies that men, regardless of their sexual orientation, retain masculine characteristics when it comes to their sexual behavior," he says. Both gay and straight men, for example, tend to prefer younger partners, in contrast to women, who gravitate toward older partners. Most men are also more likely than women to engage in casual...
