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

Similar to functional magnetic resonance imaging (fMRI), functional near-infrared
spectroscopy (fNIRS) detects the changes of hemoglobin species inside the brain, but via …

Delayed cerebral ischemia is a major predictor of poor outcomes in patients who suffer
subarachnoid hemorrhage. Treatment options are limited and often ineffective despite many …

Subarachnoid haemorrhage (SAH) causes early brain injury (EBI) that is mediated by effects
of transient cerebral ischaemia during bleeding plus effects of the subarachnoid blood …

Cerebral autoregulation is the intrinsic ability of the brain to maintain adequate cerebral
perfusion in the presence of blood pressure changes. A large number of methods to assess …

Aneurysmal subarachnoid hemorrhage (SAH) is a worldwide health burden with high fatality
and permanent disability rates. The overall prognosis depends on the volume of the initial …

Brain ultrasonography can be used to evaluate cerebral anatomy and pathology, as well as
cerebral circulation through analysis of blood flow velocities. Transcranial colour-coded …

Despite decades of study, subarachnoid hemorrhage (SAH) continues to be a serious and
significant health problem in the United States and worldwide. The mechanisms contributing …

Cerebral vasospasm has traditionally been regarded as an important cause of delayed
cerebral ischaemia (DCI) which occurs after aneurysmal subarachnoid haemorrhage, and …

Regulation of the cerebral circulation relies on the complex interplay between
cardiovascular, respiratory, and neural physiology. In health, these physiologic systems act …
