...complex picture of the body's response to stress that involves several interrelated pathways. Scientists know the most about cortisol because until now that has been the easiest part to measure. "But when one thing changes, all the others change to some degree," says Bruce McEwen, a neuroendocrinologist at Rockefeller University who has spent decades studying the biology of stress, primarily in animals. So just because you see an imbalance in one area doesn't mean you understand why it is happening. "We're learning that post-traumatic stress disorder (PTSD), burnout, chronic fatigue syndrome and fibromyalgia are all related...
These conjectures about the corpus callosum have been hard to prove because the structure's girth varies dramatically with both age and health. Studies of autopsied material are of little use because brain tissue undergoes such dramatic changes in the hours after death. Neuroanatomist Laura Allen and neuroendocrinologist Roger Gorski of UCLA decided to try to circumvent some of these problems by obtaining brain scans from live, apparently healthy people. In their investigation of 146 subjects, published in April, they confirmed that parts of the corpus callosum were up to 23% wider in women than in men. They also measured...
Animal studies provide a good deal of evidence for a biological basis of sexual orientation. Through careful manipulation of hormone levels in newborn rats, Roger Gorski, a neuroendocrinologist at UCLA, has been able to produce male rodents that demonstrate feminine behavior. Other researchers, working with mice, have noted that female fetuses that develop between two male fetuses in a litter appear to be masculinized to some degree by their brothers' testosterone. They look more like males than females, mature more slowly, have fewer reproductive cycles as adults and are less attractive to male mice...
Among the distinguished medical men on the program were Friedrich Wenckebach, Viennese heart specialist; F. G. Banting, of insulin fame; E. V. McCollum, vitamin expert of Johns Hopkins; A. B. Luckhardt, Chicago physiologist; Walter Timme, neuroendocrinologist of New York; Fred H. Albee, surgeon. The business of the Association was transacted by the House of Delegates, which has representatives by population from the affiliated medical societies of each state. The A. M. A. is widely known as a model of efficient administration under the direction of Dr. George H. Simmons, whose headquarters are in Chicago. With 88,000 members-the majority...
