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 …

It remains unclear whether orthostatic stress evokes regional differences in cerebral blood
flow. The present study compared blood flow in the internal carotid (ICA) and vertebral …

BACKGROUND Orthostatic syncope is usually attributed to cerebral hypoperfusion
secondary to systemic hemodynamic collapse. Recent research in patients with …

We sought to determine whether gravity-induced changes in intracranial pressure influence
cerebral blood flow regulation. Accordingly, nine young healthy men were studied while …

The aim of this study was to determine whether lower body negative pressure (LBNP),
combined with noninvasive methods of assessing changes in systemic and cerebral …

Postural changes impair the ability of the cerebrovasculature to buffer against dynamic
pressure fluctuations, but the mechanisms underlying this impairment have not been …

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 …

The aim of the current study was to establish the interplay between blood flow patterns
within a large cerebral artery and a downstream microvascular segment under conditions of …

Pulsatile changes in blood pressure and arterial diameter were studied noninvasively with
applanation tonometry and echo-tracking techniques at the sites of the common carotid …
