Abstract

Abstract The effects of relatively large septal lesions on schedule-induced drinking of water, quinine hydrochloride, and saccharin solutions in three rats were determined. Results indicate that septal lesions enhance schedule-induced polydipsia and decrease an apparent palatability related inhibitory effect on drinking. The absence of these effects in one control animal with extensive damage in the dorsolateral portion of hypothalamus including the zona incerta and ventral thalamic nucleus suggests that these effects might be specific to the septum.
