Patients with carotid artery stenosis may be particularly susceptible to hypotension-
associated cerebral ischemia and subsequent neurological sequelae. Measuring …

The relationship between systemic arterial pressure (SAP) and neocortical microcirculatory
blood-flow (CBF) in areas of focal cerebral ischemia was studied in 15 spontaneously …

The inability to quantify cerebral blood flow and changes in macrocirculation cross-sectional
area in all brain regions impedes robust insight into hypoxic cerebral blood flow control. We …

Previous studies have demonstrated a significant pressure gradient from carotid artery to
pial or middle cerebral arteries. This pressure gradient suggests that large cerebral arteries …

The purpose of this study was to examine regional autoregulation of blood flow in the brain
during acute hypertension. In anesthetized cats severe hypertension increased blood flow …

New Findings What is the central question of this study? Recently, the heterogeneity of the
cerebral arterial circulation has been argued. Orthostatic tolerance may be associated with …

The article discusses research being done on cerebral blood flow (CBF) regulation during
hypoxia. It examines a study by S. Ogoh and colleagues on the effect on blood flow of acute …

Autoregulation is a result of an intrinsic character of vascular smooth muscle cells. Other
factors interact with pressure to define the degree of contraction of the smooth muscle cell …

The N2O technique was used in 6 human subjects to measure cerebral blood flow and
metabolism during hypoxia and hypercapnia induced by the inhalation of 10% O2-5% CO2 …

After occlusion of an artery to the brain, hypercarbia and seizures may produce a
paradoxical reduction in cerebral blood flow to the region supplied by collateral vessels. We …
