Taste phenomena influences on stimulation of deprivation-induced fluid consumption of rats

Abstract

The dipsogenic actions of barbital and chlordiazepoxide are selectively influenced by the taste of the consummatory fluid presented to deprived rats. The potency of barbital as a consummatory stimulant is reduced relative to distilled water or tartaric acid by the use of a pleasant tasting fluid, saccharin. The potency of chlordiazepoxide as a dipsogenic agent was reduced by the use of either tartaric acid or saccharin as a consummatory fluid as compared to water. Promazine depressed deprivation-induced fluid consumption with a similar potency regardless of the consummatory fluid used.
