...flicker through the cortex, nerve cells in the developing brain crackle with purposeful activity. Like teenagers with telephones, cells in one neighborhood of the brain are calling friends in another, and these cells are calling their friends, and they keep calling one another over and over again, "almost," says neurobiologist Carla Shatz of the University of California, Berkeley, "as if they were autodialing...
...precise mechanisms by which those changes are brought about. Neural activity triggers a biochemical cascade that reaches all the way to the nucleus of cells and the coils of DNA that encode specific genes. In fact, two of the genes affected by neural activity in embryonic fruit flies, neurobiologist Corey Goodman and his colleagues at Berkeley reported late last year, are identical to those that other studies have linked to learning and memory. How thrilling, exclaims Goodman, how intellectually satisfying that the snippets of DNA that embryos use to build their brains are the very same ones that will later...
...WANTS TO BELIEVE IN THE health benefits of melatonin more than Fred Turek. A neurobiologist at Northwestern University in Evanston, Illinois, Turek has devoted two decades of his life to studying this naturally occurring substance produced by the pineal gland. He feels certain that it functions as the body's own safe and highly effective sleeping potion. But lately Turek can't shake the feeling that the world has gone melatonin mad. Based on the flimsiest scientific evidence, the subject of his research is now being trumpeted in books and magazines and on television as a cure for everything from...
There are simpler explanations--stress, for example. "Think about it," says Roger Gorski, a neurobiologist at UCLA who has studied rats' sexual behavior for 30 years. "These people undergo a lot of emotional trauma. To cut everything off to become a woman has got to be awfully stressful, and that has got to affect brain structures...
...passionate and vibrant. VR.5 is a science-fiction TV show that Patricia Highsmith might have written. For all its vividly colored effects, it is above all an exploration of the unsolved mysteries of Sydney's interior life. She is haunted by the death of her father, a secretive neurobiologist, and her journeys provide electronically sophisticated psychotherapy. On her road to analysis, however, she encounters a host of very real villains, most of them associated with the Committee, an agency with suspect motives that coerces Sydney to work...
