Uncovering the impact of the cardiovascular system on cerebrovascular health using MRI

Experimental Physiology, EarlyView.
Abstract Human cerebrovasculature is finely tuned to enable local changes in blood flow to meet the brain's demands, whilst protecting the brain from systemic changes in blood pressure, both acutely during a heartbeat and chronically over time. This review summarises cerebrovascular structure and function, their role in disease and neurodegeneration ...

Optimizing cerebrovascular endothelial health through shear stress modulation

Experimental Physiology, EarlyView.
Abstract The endothelium plays a pivotal role in regulating cerebrovascular blood flow, and its dysfunction increases the risk of cerebrovascular disease. Endothelial shear stress, a primary mechanical stimulus for endothelial nitric oxide production, is a key modulator of vascular adaptation.

Linking dynamic cerebral autoregulation and inhibitory executive function: Role of modifiable behaviours

Experimental Physiology, EarlyView.
Abstract Dynamic cerebral autoregulation (dCA) stabilises cerebral blood flow (CBF) against rapid fluctuations in perfusion pressure and may serve as a key physiological mediator of cognitive function. Inhibitory executive function, a core domain essential for goal‐directed behaviour, is influenced by modifiable lifestyle factors such as physical ...

Modulation of cerebral blood flow and cognition by hyperthermia and hypoxia: An electroencephalographic event‐related potentials perspective

Experimental Physiology, EarlyView.
Abstract Cerebral blood flow (CBF) is essential for sustaining neuronal metabolism and cognitive performance; however, the precise relationship between perfusion and cognition remains unclear. Although ageing and disease are associated with progressive declines in CBF and cognitive impairment, the acute effects of altered CBF under environmental ...
