Angiotensin and the brain

Abstract
A brief account for the renal renin‐angiotensin system (RAS), its inhibitors and receptors, as for the presence of an intrinsic cerebral RAS is initially provided. The review is then focused upon the circumventricular organs as cerebral targets for blood‐borne angiotensin II (Ang II) and on centrally mediated Ang II effects. These concern influences upon the cardiovascular system, water balance, sodium balance, and ACTH‐cortisol secretion.
