| Abstract: | 1. Oxytocin as well as vasopressin is released in rats following systemic osmotic stimulation. There is evidence that, in the rat, oxytocin is a natriuretic hormone. 2. Osmotically-induced activation of oxytocin and vasopressin cells and osmotically-induced hormone secretion are diminished by ablation of tissue in the region anterior and ventral to the third ventricle (AV3V region). 3. The nature and identity of the osmoreceptors subserving oxytocin and vasopressin release are discussed. |
