title: Oropharyngeal control of drinking in rats.
abstract: Drinking was studied in water-deprived rats with chronic intragastric fistulas. Sham drinking, by which the ingested water was immediately lost through the open gastric fistula, was approximately four times greater than normal drinking. This proportion held across different levels of water deprivation, following 5-ml intragastric preloads of water or isotonic saline or ingestion of isotonic saline. The contribution of oropharyngeal controls in the normal drinking of rats is discussed and is compared with that of other species.
