Impaired Windkessel function and proximal aortic stiffness: Linking vascular ageing to cognitive decline

open access: yesExperimental Physiology, EarlyView.
Abstract Central arterial stiffening, particularly of the proximal aorta, is increasingly recognised as a pivotal contributor to cardiovascular disease, dementia, and mild cognitive impairment. Loss of Windkessel function amplifies pulsatile pressure, reduces diastolic perfusion and accelerates microvascular damage in the brain.

Microelectrode recordings from the human cervical vagus nerve during maximal breath‐holds

open access: yesExperimental Physiology, EarlyView.
Abstract Voluntary breath‐holds can be sustained for a long time following training, but ultimately, regardless of duration, the asphyxic break‐point is reached and the apnoea terminated. The physiological changes occurring during the apnoea include a marked increase in sympathetically‐mediated vasoconstriction in non‐essential organs, such as skeletal
