CNS Regulation of Salt and Water Intake

Abstract
The brain has evolved a number of mechanisms to maintain body fluid balance. They include the sensation of thirst, which stimulates water intake, the secretion of vasopressin, which helps prevent water loss, and the secretion of aldosterone, which helps prevent sodium depletion. In the research described here, all three mechanisms are shown to be mediated by the actions of angiotensin on the brain.
