From: Cerebral blood flow regulation and cognitive function: a role of arterial baroreflex function
Effect of cute hypervolemia on CBF and peripheral vasculature via baroreflex. During parabolic flight, acute loading of baroreceptors drastically evokes a decrease in sympathetic nerve activity and consequently reduces peripheral vascular resistance, and the middle cerebral artery mean blood velocity (MCA Vmean) remains unchanged. This change in total vascular conductance (TVC) via the arterial baroreflex is associated with a change in the contribution of the cardiac output (CO) to MCA Vmean.
