Brain function critically depends on a close matching between metabolic demands,
appropriate delivery of oxygen and nutrients, and removal of cellular waste. This matching …

Neurovascular coupling reflects the close temporal and regional linkage between neural
activity and cerebral blood flow. Although providing mechanistic insight, our understanding …

Cerebral blood flow (CBF) is rigorously regulated by various powerful mechanisms to
safeguard the match between cerebral metabolic demand and supply. The question of how …

This review presents lower body negative pressure (LBNP) as a unique tool to investigate
the physiology of integrated systemic compensatory responses to altered hemodynamic …

Transcranial Doppler (TCD) is a noninvasive ultrasound (US) study used to measure
cerebral blood flow velocity (CBF‐V) in the major intracranial arteries. It involves use of low …

The response of cerebral vasculature to exercise is different from other peripheral
vasculature; it has a small vascular bed and is strongly regulated by cerebral autoregulation …

To test the hypothesis that spontaneous changes in cerebral blood flow are primarily
induced by changes in arterial pressure and that cerebral autoregulation is a frequency …

Background and Purpose—The relationship between middle cerebral artery (MCA) flow
velocity (CFV) and cerebral blood flow (CBF) is uncertain because of unknown vessel …

Cerebral autoregulation (CA) refers to the properties of the brain vascular bed to maintain
cerebral perfusion despite changes in blood pressure (BP). Whereas classic studies have …

Assessment of cerebral autoregulation is an important adjunct to measurement of cerebral
blood flow for diagnosis, monitoring or prognosis of cerebrovascular disease. The most …
