Purpose To detect oscillations of the cerebrospinal fluid (CSF) flow related to the heartbeat
and frequencies lower than 0.6 Hz and to compare these oscillations of CSF and blood flow …

OBJECTIVE: Induced hypertension is commonly used to improve cerebral perfusion, but this
treatment may have the deleterious side effect of raising intracranial pressure (ICP). We …

Vasovagal syncope may be due to a transient cerebral hypoperfusion that accompanies
frequency entrainment between arterial pressure (AP) and cerebral blood flow velocity …

Transcranial Doppler measurements of blood flow velocity permit an assessment of
variations in intracranial hemodynamics in response to acute arterial pressure variations …

There is no general agreement regarding several aspects of the role of the sympathetic
system on cerebral haemodynamics such as extent of effectiveness, operational range and …

The transient hyperaemic response (THR) of blood flow velocity in the middle cerebral artery
(vmca), measured by transcranial Doppler ultrasonography (TCD), can be used to assess …

BACKGROUND AND PURPOSE: Perfusion imaging with dynamic susceptibility contrast MR
imaging (DSC-MRI) has been used to evaluate hemodynamic status in patients with …

Understanding the physiology of the cerebral and spinal cord circulation is of vital
importance to the practice of neuroanesthesia. In the absence of major advances in …

Abstract A three‐dimensional (3D) T1‐weighted sequence was used to acquire high spatial
resolution whole brain images in rats before and after the injection of an intravascular …

The time constant of cerebral arterial bed (in brief time constant) is a product of brain arterial
compliance (Ca) and resistance (CVR). We tested the hypothesis that in normal subjects …
