Abstract
Regional spinal cord blood flow was measured in rats during the sleep- wake cycle with the use of radioactive microspheres. Spinal cord blood flow decreases from wakefulness to quiet (synchronized) sleep while i ncreasing in active (desynchronized) sleep. Blood-flow changes depend on changes in vascular resistance whose mechanisms have yet to be eluc idated. Blood-gas tension or mean arterial pressure, however, do not p lay a relevant causal role.
