Cerebrovascular reactivity (CVR) is an indicator of cerebrovascular reserve and provides
important information about vascular health in a range of brain conditions and diseases …

Cerebrovascular reactivity (CVR) magnetic resonance imaging (MRI) probes cerebral
haemodynamic changes in response to a vasodilatory stimulus. CVR closely relates to the …

Accurate estimates of the BOLD hemodynamic response function (HRF) are crucial for the
interpretation and analysis of event-related functional MRI data. To date, however, there …

Intact, coordinated, and precisely regulated cerebrovascular responses are required for the
maintenance of cerebral metabolic homeostasis, adequate perfusion, oxygen delivery, and …

Given adequate perfusion pressure and nonlimiting intracranial or venous pressure,
cerebral blood flow (CBF) is regulated to match cerebral metabolic rate of oxygen (CMRO2) …

Concussion is a form of traumatic brain injury (TBI) that presents with a wide spectrum of
subjective symptoms and few objective clinical findings. Emerging research suggests that …

Brain aging and associated neurodegeneration constitute a major societal challenge as well
as one for the neuroimaging community. A full understanding of the physiological …

The topological characteristics of functional networks, derived from measurements of resting-
state connectivity in gray matter (GM), are associated with individual cognitive abilities or …

Cerebrovascular reactivity and cerebral autoregulation are two major mechanisms that
regulate cerebral blood flow. Both mechanisms are typically assessed in either supine or …

Cerebrovascular reactivity (CVR) is a measure of vascular response to a vasoactive
stimulus, and can be used to assess the health of the brain vasculature. In this current study …
