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 …

Cerebrovascular reactivity is the change in cerebral blood flow in response to a vasodilatory
or vasoconstrictive stimulus. Measuring variations of cerebrovascular reactivity between …

Slow changes in systemic brain physiology can elicit large fluctuations in fMRI time series,
which manifest as structured spatial patterns of temporal correlations between distant brain …

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 …

In resting state fMRI, it is necessary to remove signal variance associated with noise
sources, leaving cleaned fMRI time-series that more accurately reflect the underlying …

We assessed the convergent validity of commonly applied metrics of cerebral autoregulation
(CA) to determine the extent to which the metrics can be used interchangeably. To examine …

The blood oxygenation level dependent (BOLD) signal measures brain function indirectly
through physiological processes and hence is susceptible to global physiological changes …

White matter (WM) comprises about half of the brain and its dysfunction is implicated in
many brain disorders. While structural properties in healthy and diseased WM have been …

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