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

Cerebral autoregulation (CA) refers to the control of cerebral tissue blood flow (CBF) in
response to changes in perfusion pressure. Due to the challenges of measuring intracranial …

Cerebral blood flow (CBF) and cerebral autoregulation (CA) are critically important to
maintain proper brain perfusion and supply the brain with the necessary oxygen and energy …

Cerebral autoregulation is the intrinsic ability of the brain to maintain adequate cerebral
perfusion in the presence of blood pressure changes. A large number of methods to assess …

Cerebral autoregulation is a homeostatic process that regulates and maintains cerebral
blood flow (CBF) constant across a range of blood pressures. The original concept was …

There is considerable utility in the use of transcranial Doppler ultrasound (TCD) to assess
cerebrovascular function. The brain is unique in its high energy and oxygen demand but …

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 …

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 …

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 …

Background and Purpose—Cerebral autoregulation may become impaired after stroke. To
provide a review of the nature and extent of any autoregulation impairment after stroke and …
