Quantification of the cerebral pressure–flow relationship directional sensitivity: Reliability of shorter repeated squat–stand durations

Experimental Physiology, Volume 111, Issue 2, Page 357-374, 1 February 2026.
Abstract The magnitude of changes in middle cerebral artery mean blood velocity (MCAv) is attenuated when mean arterial pressure (MAP) increases compared with when MAP decreases. This directional sensitivity has been characterized using a time‐corrected ratio calculated on MCAv and MAP changes induced by repeated squat–stands (RSS) at 0.05 and 0.10 Hz ...

Effect of moderate altitude and nocturnal oxygen therapy on cerebrovascular function in patients with COPD: A randomized, crossover trial at 2048 m

Experimental Physiology, Volume 111, Issue 2, Page 527-538, 1 February 2026.
Abstract We investigated whether nocturnal oxygen therapy improves next‐day cerebrovascular function in lowlanders with chronic obstructive pulmonary disease (COPD) staying at moderate altitude. This randomized, placebo‐controlled single‐blind crossover trial was performed in moderate‐to‐severe COPD patients [forced expiratory volume in 1 s (FEV1 ...

Longitudinal sex differences in cerebrovascular ageing in older adults: results from the brain in motion study

The Journal of Physiology, Volume 604, Issue 3, Page 1088-1112, 1 February 2026.
Abstract figure legend Longitudinal assessment of sex differences in cerebrovascular ageing over a ∼6 year period: the Brain in Motion study. Cerebrovascular function was assessed at baseline (T1) and at a follow‐up (T2) ∼6 years later, at rest, during euoxic hypercapnia and while engaging in submaximal exercise. Over the follow‐up period females had a

Fetal Cerebral Blood Flow (Dys)Autoregulation

Diagnostics
Background: As a noble and extremely sensitive organ, particularly during in utero development, the brain has intrinsic systems to reduce the risk of cerebral damage in cases of insult, such as energy deprivation, due to a mechanism of positive balance in cerebral oxygen–energy substrate demand and supply.
