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

This study validates transcranial Doppler sonography (TCD) for determination of the lower
limit of cerebral blood flow (CBF) autoregulation and establishes a relation between global …

The coupling of brain cell function to the vascular system is the basis for a number of
functional neuroimaging methods relevant for human studies. These include methods as …

Cerebrovascular reactivity, defined broadly as the ability of brain parenchyma to adjust
cerebral blood flow in response to altered metabolic demand or a vasoactive stimulus, is …

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

Imaging of scattered and reflected light from the surface of neural structures can reveal the
functional architecture within large populations of neurons. These techniques exploit, as one …

Oscillations of arterial blood pressure (ABP) and cerebral blood flow velocity (CBFV) can be
used for non-invasive assessment of cerebral autoregulation using transfer function …

Brain perfusion is tightly coupled to neuronal activity, is commonly used to monitor normal or
pathological brain function, and is a direct reflection of the interactions that occur between …

Functional magnetic resonance imaging (fMRI) is based on the coupling between neural
activity and changes in the concentration of the endogenous paramagnetic contrast agent …

Abstract Purpose of Review Cerebral autoregulation (CA) is a mechanism that maintains
cerebral blood flow constant despite fluctuations in systemic arterial blood pressure. This …
