ABSTRACT
At present our knowledge of the function of various brain regions is analogous to the aversive situation, discussed in Chapter 8, of having overuse of the bottom neurons of a pyramid and little activity in the top neurons. An enormous amount of research is being done on the question. To review all the studies, for instance, on the ventromedial hypothalamic nucleus would fill a book the size of this one. This is only one of many hypothalamic nuclei, and the hypothalamus is only one small region in the brain.
