abstract
Female rats with lesions of the ventromedial hypothalamus (VMH) overate and gained more body weight than same-diet control rats, following extended maintenance on a ground-chow diet adulterated with an equal weight of cellulose. Adulteration with cellulose clearly decreased diet palatability, because control rats fed the cellulose-adulterated diet ate and weighed less than control rats fed the unadulterated ground-chow diet. The overeating of a less palatable diet by VMH rats is consistent with the hypothesis that VMH lesions increase hunger motivation. 1978, Psychonomic Society, Inc.. All rights reserved.
