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

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

Cerebrovascular reactivity (CVR) is defined as the ability of vessels to alter their caliber in
response to vasoactive factors, by means of dilating or constricting, in order to increase or …

The human brain constitutes 2% of the body's total mass but uses 20% of the oxygen. The
rate of the brain's oxygen utilization can be derived from a knowledge of cerebral blood flow …

Background Cerebrovascular reserve, the potential capacity of brain tissue to receive more
blood flow when needed, is a desirable marker in evaluating ischemic risk. However, current …

Background Postoperative delirium (POD) is a common surgical complication associated
with increased morbidity and mortality in elderly. Although the underlying mechanisms …

Significance: Near-infrared spectroscopy (NIRS) combined with diffuse correlation
spectroscopy (DCS) provides a noninvasive approach for monitoring cerebral blood flow …

Introduction Many consequences of cerebrovascular disease are identifiable by magnetic
resonance imaging (MRI), but variation in methods limits multicenter studies and pooling of …

Objectives Perivascular spaces have been involved in neuroinflammatory and
neurodegenerative diseases. Upon a certain size, these spaces can become visible on …

Accurate identification of brain function is necessary to understand the neurobiology of
cognitive ageing, and thereby promote well-being across the lifespan. A common tool used …
