Military pilots risk their lives during training and operations. Advancements in aerospace
engineering, flight profiles, and mission demands may require the pilot to test the safe limits …

Abstract Persons with the Ehlers–Danlos syndromes (EDS) report a wide range of
respiratory symptoms, most commonly shortness of breath, exercise limitation, and cough …

Key points We investigated the influence of arterial () with and without acutely elevated
arterial pH and bicarbonate ([HCO3–]) on cerebral blood flow (CBF) regulation in the …

Quantification of the effect of breathing on the cerebral circulation provides a better
mechanistic understanding of the brain's circulatory system and is important in the early …

Early definitive airway protection and normoventilation are key principles in the treatment of
severe traumatic brain injury. These are currently guided by end tidal CO2 as a proxy for …

Systemic physiological dynamics, such as heart rate variability (HRV) and respiration
volume per time (RVT), are known to account for significant variance in the blood oxygen …

Objective. Closed loop cardiovascular (CV) and cerebrovascular (CBV) variability
interactions are assessed via transfer entropy (TE) from systolic arterial pressure (SAP) to …

Functional magnetic resonance imaging (fMRI) is a central tool for investigating human brain
function, organization and disease. Here, we show that fMRI-based estimates of functional …

Regulation of cerebral blood flow during exercise in youth is poorly understood. This study
investigated the cerebrovascular and ventilatory responses to a ramp incremental cycle test …

The aim of this study was to compare the kinetic response of middle cerebral artery blood
velocity (MCAv) to moderate-and heavy-intensity cycling in adults, and explore the …
