Cerebral blood flow (CBF) regulation can be impaired in acute ischemic stroke but the
combined effects of dynamic cerebral autoregulation (CA), CO2 cerebrovascular reactivity …

Neurovascular coupling (NVC) and dynamic cerebral autoregulation (dCA) are both
impaired in the acute phase of ischemic stroke, but their reciprocal interactions are difficult to …

Background: Acute stroke is known to impair cerebral blood flow (CBF) regulation, but the
longitudinal changes of these effects have been poorly reported. The main CBF regulatory …

PaCO2 affects cerebral blood flow (CBF) and its regulatory mechanisms, but the interaction
between neurovascular coupling (NVC), cerebral autoregulation (CA), and cerebrovascular …

BACKGROUND: Cerebrovascular reactivity (CVR) testing with CO2 challenge is used
clinically as a measure of cerebrovascular reserve. However it is not known whether CVR …

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

The effects of physical activity on cerebral blood flow (CBF) and cerebral autoregulation
(CA) have not yet been fully evaluated. There is controversy as to whether increasing heart …

Cerebrovascular autoregulation is evaluated from spontaneous fluctuations in mean flow
velocity (MFV) by transcranial Doppler ultrasound of the middle cerebral artery (MCA) with …

Motor stimulation induces a neurovascular response that can be detected by continuous
measurement of cerebral blood flow (CBF). Simultaneous changes in arterial blood pressure …

The new two-breath CO2 method was employed to test the hypotheses that small alterations
in arterial Pco2 had an impact on the magnitude and dynamic response time of the CO2 …
