Abstract: Marked variations in food intake have been described in various species following injury to certain parts of the hypothalamus, including an increased food intake or hyperphagia caused by lesions in the medial hypothalamus, especially lesions in or ventrolateral to the ventromedial nucleus; this hyperphagia leads to obesity. " 1418 ' 20 24 A decrease or complete inhibition of food intake has also been reported as an incidental finding in animals with hypothalamic lesions, by Hetherington and Ranson16 in rats, and by Clark, Magoun, and Ranson'0 during their study of temperature regulation in cats. Similar observations were also made in cats by Ingram, Barris, and Ranson, " by Ranson ' in monkeys, and by Anand and Brobeck ' in certain rats which were being prepared for studies of food intake and activity. The present investigation, therefore, was undertaken as an attempt to localize in the hypothalamus the areas the destruction of which leads to diminution or failure of eating with emaciation, as destruction of certain other areas leads to overeating and obesity. As a result of these studies a small, welllocalized
