Some professors say they won’t let student contact be the factor in the equation that is diminished to make room for time for being a public intellectual. MIT neuroscientist Steven Pinker, whom FM tracked down on the West Coast in the midst of a six-week tour to promote his new book, The Blank Slate, says he makes a point of answering students’ e-mails on the same day that he receives them. But still, as Pinker admits, in order to be an effective public intellectual, “something?...
Ritter attended Oberlin College, where he studied to be a neuroscientist, but songwriting was his real love. He hopes that his lyrics will give listeners a new way to think about something like love; he hopes his ideas become part of peoples’ memories. Despite this aspiration, Ritter is wary of the “confines” that big record labels with their powerful marketing can impose on artists. “Music first and everything else later,” he says...
...essence, researchers are discovering, the digestive system tells the brain how much to eat by pumping various hormones, one of which is PYY, into the bloodstream. "There are at least half a dozen signals that we know about," says Michael Cowley, a neuroscientist at the Oregon National Primate Center in Beaverton and one of the co-authors of the Nature paper. Some of these biological traffic lights work in a very short time frame, affecting when you start and stop a meal. Some, like leptin, work over the longer term by helping the brain monitor how much fatty tissue...
...system in the body to fight like the devil or run like crazy. It's not designed to be accurate, just fast. If you have ever gone hiking and been startled by a snake that turned out to be a stick, you can thank your amygdala. Joseph LeDoux, a neuroscientist at New York University, calls it "the hub in a wheel of fear...
...also be that an entirely different part of the brain holds the key to understanding anxiety. Michael Davis, a behavioral neuroscientist at Emory University in Atlanta, has spent six years studying a pea-size knot of neurons located near the amygdala with an impossible name: the bed nucleus of the stria terminalis, or BNST. Rats whose BNST has been injected with stress hormones are much jumpier than those that have got a shot in their amygdala. Could the BNST be at the root of all anxiety disorders? The clues are intriguing, but as scientists are so fond of saying, more...
