But without the other stimuli of the 1960s, students are far less likely to muster significant opposition to the way their schools operate. The pressure that foster pervasive careerism only further decrease the chances that students will spend much time on issues they can easily dismiss as "the way things...
...When released into the cultural ear, these stimuli initiate festive tendencies which manifest themselves in actions such as giggling, excessive drinking, and sleeping (which comes about because of the dormative principle). Occasionally these stimuli cause a Scrooge-like behavior which reflects an excessive depressed state...
...danger, people grow numb to the meaning of the arms race by a perverse process of "adaptation" or "habituation." As Frank puts it, "if an animal kept attending to every environmental stimulus, its capacity to sense new dangers would be swamped, therefore the animal stops attending to continuing stimuli. So do humans...
...works as well-or better. Scientists have long reasoned that if good taste and smell can increase appetite, terrible taste and odor, or one flavor eaten over and over, should be boring enough to decrease it. Last week, at an international conference on "The Determination of Behavior by Chemical Stimuli," a pair of biologists reported findings suggesting that any tedious diet helps weight loss. If it were possible to eat one food all the time, according to Israeli Nutritional Biochemist Michael Nairn, all but the genetically obese would quickly shed pounds...
Still, the most dramatic impact of PET scanning so far has been in studies of the brain. The technique is painlessly providing detailed information about how a normal brain reacts biochemically to such stimuli as the eyes seeing light, the ears hearing a story and even the movement of an arm or a leg. For example, when a subject moves his right hand, the PET scan indicates increased glucose use by the region of the left side of the brain controlling the action. Physicians have begun to use PET scanning in determining therapy for people who have had strokes...
