...rare and radical surgery that has wrought such changes, Dr. Hendrick cuts a trap door in the skull, removes the entire neocortex (new brain) and hippocampal area on one side (see diagram), stopping at the midbrain just above the hypothalamus. He puts nothing into the huge cavity that results, because it soon fills up with cerebrospinal fluid. The operation, he says, "is not exciting-it's terrifying, especially, on young babies. They don't have much blood anyway, and we have to get into an area that's all blood vessels. And you have...
...assumption that there is a straight-line relationship between energy expenditure and appetite is an over simplification, says Dr. Mayer. Appetite is controlled by two parts of the brain's hypothalamus. One is a hunger center, the other a satiety center. When energy output is in the middle range, the centers balance neatly, switching one another on and off. But not so at the ends of the activity scale...
...autopsy showed that Whitman had a pecan-size brain tumor, or astrocytoma, in the hypothalamus region, but Pathologist Coleman de Chenar said that it was "certainly not the cause of the headaches" and "could not have had any influence on his psychic behavior." A number of Dexedrine tablets?stimulants known as "goofballs" ?were found in Whitman's possession, but physicians were not able to detect signs that he had taken any before he died...
...Bark & New. What is generally agreed is that the most primitive emotions and reactions, such as hunger and sex drives, are experienced in the hypothalamus (see diagram). In general, the higher the functions, the higher their seats in the brain-rising through the thalami and their branches, and the basal ganglia, to the paleocortex ("old bark"), which man shares with the higher animals...
Brain researchers think that they have traced the 6-14 peaks to an abnormality in the lower brain-either in the thalamus or the hypothalamus. This may be the result of heredity, head injury or brain inflammation. Describing Steve's case and another like it in the Archives of General Psychiatry, Dr. Woods does not suggest that the brain abnormality is the cause of violence. He reasons by analogy with epilepsy that victims must have both the abnormality and the emotional disturbance to provoke an attack...
