Cerebrovascular flow‐mediated dilation in humans: Methodological challenges, physiological interpretation and future integrations

open access: yesExperimental Physiology, EarlyView.
Abstract Arterial shear‐mediated vasodilation is a well‐established measure of endothelial function and serves as a critical biomarker for cardiovascular disease risk. Endothelial function can be measured using a variety of experimental methodologies; however, the most widely adopted technique is ultrasound‐based flow‐mediated dilation (FMD), in which ...

A comparison of normobaric and hypobaric hypoxia effects on cerebrovascular response pre and post maximal exercise

open access: yesExperimental Physiology, EarlyView.
Abstract A lack of consensus remains on whether normobaric hypoxia (NH) and hypobaric hypoxia (HH) may differentially impact physiological factors affecting cerebrovascular regulation, particularly with an additional strenuous exercise component. We sought to compare the acute effects of NH and HH on global cerebral blood flow (gCBF) at an altitude ...

Mechanisms regulating cerebral perfusion during running exercise: Influence of foot strike‐induced pulsatility oscillations, CO2 reactivity and BP

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Young, healthy males and females completed an incremental running test, demonstrating a progressive increase in middle cerebral artery blood velocity (MCAv) up to maximal exercise despite reductions in end‐tidal CO2. To investigate the underlying mechanism, foot‐strike timing was synchronized to the diastolic phase of the cardiac

The role of acid‐base balance in cerebrovascular and ventilatory responses to CO2 during 10 h normobaric hypoxia

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend During 10 h exposures to normobaric hypoxia exposure there was a selective leftward shift in ventilatory response to hyperoxic hypercapnic rebreathing, but not the cerebrovascular response. The key findings are that the resetting of the central chemoreflex to lower PCO2${P_{{\mathrm{C}}{{\mathrm{O}}_2}}}$ during early hypoxic ...

Energetic microdomains and the vascular control of neuronal and muscle excitability: Toward a unified model

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend The capillary–mitochondria–ion channel (CMIC) axis scales structural resources to match functional workload. (Left) In settings of restricted energetic capacity (e.g. cortical neurons), sparse capillary networks and modest mitochondrial pools set a lower energetic ceiling, sufficient to support phasic, low‐workload excitability.
