The role of systemic hydration in the acquisition of schedule-induced polydipsia by rats

Intragastric water prevented the acquisition of schedule-induced polydipsia by rats despite its lack of effect on established polydipsia. When drinking was maintained (by the prior induction of dry-mouth drinking) schedule-induced polydipsia was acquired in spite of intragastric hydration. The resul...

Zusammenfassung:Intragastric water prevented the acquisition of schedule-induced polydipsia by rats despite its lack of effect on established polydipsia. When drinking was maintained (by the prior induction of dry-mouth drinking) schedule-induced polydipsia was acquired in spite of intragastric hydration. The results suggest that polydipsia is an acquired, operant, behavior rather than an exaggeration of an existing behavior.
