Regulation of Cerebral Blood Flow [PDF]

open access: yesInternational Journal of Vascular Medicine, 2011
The control of cerebral blood flow is complex, and only beginning to be elucidated. Studies have identified three key regulatory paradigms. The first is cerebral pressure autoregulation, which maintains a constant flow in the face of changing cerebral ...

Vestibular effects on cerebral blood flow [PDF]

open access: yesBMC Neuroscience, 2008
AbstractHumans demonstrate a number of unique adaptations that allow the maintenance of blood pressure and brain blood flow after transition to the upright position. While these adaptations maintain heart-level mean arterial pressure similar to supine values, the brain remains ~30 cm above the heart, resulting in a ~25% decrease in perfusion pressure ...

Cerebral blood flow velocity is associated with endothelial function in men [PDF]

open access: yesJournal of Men's Health, 2021
Background and objective: Reduction in cerebral blood flow with aging leads to cognitive decline and brain atrophy. Cerebrovascular hemodynamics are associated with vascular function.

Nimodipine augments cerebrovascular reactivity in aging but runs the risk of local perfusion reduction in acute cerebral ischemia

open access: yesFrontiers in Aging Neuroscience, 2023
IntroductionThe efficacy of cerebrovascular reactivity (CVR) is taken as an indicator of cerebrovascular health.Methods and ResultsWe found that CVR tested with the inhalation of 10 % CO2 declined in the parietal cortex of 18-20-month-old rats.

Modeling of intracranial vessels and Simulation of cerebral blood flow [PDF]

open access: yesE3S Web of Conferences, 2020
The stable regulation of cerebral blood flow plays an important role in the normal operation of brain function. The disturbance of cerebral blood flow automatic regulation will lead to brain injury and lead to cerebrovascular disease. Therefore, it is of

Comparison of cerebral blood flow in subjects with and without chronic obstructive pulmonary disease from the population-based Rotterdam Study

open access: yesBMJ Open, 2021
Objectives Patients with chronic obstructive pulmonary disease (COPD) are at increased risk of cerebrovascular disease, which might be associated with decreases in cerebral blood flow. Since studies examining cerebral blood flow in COPD remain scarce and

Study of the relationship between regional cerebral saturation and pCO2 changes during mechanical ventilation to evaluate modifications in cerebral perfusion in a newborn piglet model [PDF]

open access: yesBrazilian Journal of Medical and Biological Research, 2022
Near-infrared spectroscopy (NIRS) could be a useful continuous, non-invasive technique for monitoring the effect of partial pressure of carbon dioxide (PaCO2) fluctuations in the cerebral circulation during ventilation.

The effect of absent blood flow on the zebrafish cerebral and trunk vasculature

open access: yesVascular Biology, 2021
The role of blood flow in vascular development is complex and context-dependent. In this study, we quantify the effect of the lack of blood flow on embryonic vascular development on two vascular beds, namely the cerebral and trunk vasculature in ...
