The authors evaluated representations of discretely activated, neighboring brain regions
using real-time optical intrinsic signals by transcranial imaging with 540-nm and 610-nm …

Regional cerebral blood flow (rCBF) was measured in rats to define the autoregulatory
response at different levels of hypertension. Mean arterial blood pressure (MABP) was …

Central pulse pressure (PP) is the sum of forward and backward traveling pressure waves
that have been associated with cardiovascular disease (CVD) risk. However, previous …

The objective of the study was to investigate the feasibility of using computational fluid
dynamic modeling (CFD) with noninvasive ultrasound measurements to determine time …

Variations of blood flow velocity in the left and right middle cerebral arteries (MCA) were
measured in 20 hypotensive women and 20 normotensive control subjects during emotional …

We developed and characterized a model of global forebrain ischaemia in ratspermitting
control of CBF at any desired ischaemic level with minimum surgery and without …

This study was performed to determine the effects of atherosclerosis on cerebral vascular
responses to hypercapnia and hypotension. We studied nine normal and eight …

Cerebrovascular reactivity can be measured as the cerebrovascular flow response to a
hypercapnic challenge. The many faceted responses of cerebral blood flow to combinations …

Understanding neurovascular coupling is a prerequisite for the interpretation of results
obtained from modern neuroimaging techniques. This study investigated the hemodynamic …

The basilar artery and its branch arterioles dilate actively in response to a marked decrease
in blood pressure and maintain cerebral blood flow (CBF) to the brain stem. We tested the …
