Abstract

Electrolytic lesions in the ventral hypothalamus of 28 adult male white‐crowned sparrows interrupted photoperiodically induced hyperphagia and fat deposition. Lesions in posterior regions of the infundibular nuclear complex or median eminence (22 birds) eliminated both the fattening response and testicular recrudescence. Lesions restricted to the anterior division of the median eminence or the tractus hypophyseus (6 birds) eliminated the fattening response only.

Glucocorticoids have a wide array of actions in vertebrates. Daily fluctuations in basal levels of glucocorticoids are thought to regulate homeostatic mechanisms. In contrast, elevated levels secreted in response to stress stimulate changes in physiology and behavior. These changes are thought to ai
