Autoregulation of the cerebral circulation is the regulating mechanism that keeps cerebral
blood flow (CBF) constant within wide limits of arterial pressure. The lower limit is defined as …

The objective of this study was to test the hypothesis that cerebral artery autoregulatory
responses to increasing transmural pressure depend on the pre-existing level of vascular …

Although the primary emphasis of research on spontaneously hypertensive rats (SHR) tends
to be on adult animals, the young SHR can have a mean arterial pressure that is elevated …

This experiment is the first to compare cerebral vasomotor reactivity in the supra‐and infra‐
tentorial regions in baseline conditions and during progressive acute intracranial …

New Findings• What is the central question of this study? Does hypoxia enhance blood flow
to all parts of the brain uniformly?• What is the main finding and its importance? During …

We tested the hypothesis that constriction of cerebral arterioles during acute increases in
blood pressure is attenuated by activation of potassium (K+) channels. We tested the effects …

We used positron emission tomography to examine retrospectively the effects of blood
pressure on regional cerebral blood flow and oxygen metabolism in seven normotensive …

Acute increases in arterial blood pressure, beyond the autoregulatory capacity of cerebral
blood vessels, produce an increase in cerebral blood flow, passive dilatation of cerebral …

The goal of this study was to investigate factors that contribute to reductions in internal
diameter of large and small cerebral arteries during chronic hypertension. We measured …

The aim of our study was to evaluate by transcranial Doppler ultrasonography the dynamics
of blood flow velocity changes in the middle cerebral artery during and after hypocapnia …
