Abstract

In the intact cat desynchronised sleep induces arterial hypotension and mesenteric vasodilatation, whereas in limb muscles vasoconstriction occurs because of the concurrent action of a spinal vasoconstriction reflex. After sino-aortic denervation arterial hypotension is exaggerated and mesenteric vasodilatation is greater, while the muscular bed of the limbs also becomes vaso-dilated rather than constricted. It is concluded that during desynchronised sleep the sino-aortic afferents act to check a central influence inhibiting vasoconstrictor tone both in the viscera and muscles: thus an excessive fall in blood pressure is prevented by avoiding a too large visceral vasodilatation and by unmasking the vasoconstrictor action of the spinal reflex in the limbs.
