...carefully and respond while on a cell phone creates 'interference' with the task at hand, driving in this case, and our research shows that we have limited cognitive resources to multitask," says Arthur Kramer, director of the Biomedical Imaging Center at the University of Illinois. When demand for our "neural resources" exceeds supply, the result is decreased performance - scanning less attentively for pedestrians, for example, or failing to maintain a lane or speed...
...while that kids' brains are programmed to do the wave. The cortex, or outer layer of gray matter--which is responsible for such things as planning movement and suppressing inappropriate thoughts or actions--thickens from back to front during childhood and then thins out in adolescence, as unused neural connections go the way of football fans' empty beer cups. Thanks to nifty imaging techniques, the point at which the cortex reaches peak thickness is now recognized as an early milestone in brain maturation. But in a surprising new study, kids with attention-deficit/hyperactivity disorder (ADHD)--which affects...
Most software firms, of course, promise to make their clients more efficient. But NuTech claims that its products--developed by using AI technologies such as neural networks, fuzzy logic and evolutionary computing--can monitor each player continuously in a supply-and-demand equation, consider the millions of ways each player's decisions impact the business and then suggest the best ways to fine-tune a client's operations. "All our products have the common characteristic of increasing profits and decreasing costs," especially in the targeting of prospective customers, says Matthew Michalewicz, 26, NuTech's chief executive...
Still, there is evidence that hormone blockers can cause infertility. Cheryl Sisk, the head of neuroscience at Michigan State University, who studies the impact of pubertal hormones on neural development, adds that it's also too soon to know how delaying puberty plays into brain growth. Others worry about intervening with children before their gender identity is fully formed. Kenneth Zucker, a child psychologist at the Centre for Addiction and Mental Health in Toronto, notes that his studies indicate that comparatively few gender-variant children--about 12% of girls and 20% of boys--grow into transgender adults. "Gender development...
...tell if two wires cross or are just getting very close and veering off,” he said. “Wiring will be much easier when every wire is a different color.” Although the Harvard team has already used the technique to study the neural circuitry in mice, the researchers hope to further improve the method. “There are some technical limitations, so we would like to make a better Brainbow,” Lichtman said. “One way is to ensure that every nerve cell in the brain is colored...
