Sex differences in cerebral pulsatility and damping: A 4D flow MRI study
Experimental Physiology, EarlyView.Abstract Cerebral pulsatility is a potential marker of cerebrovascular health, yet little is understood about sex differences in cerebral pulsatility with age, especially within different cerebral arteries. Additionally, cerebral damping can blunt cerebral pulsatility and might decline with age.

Experimental Physiology, EarlyView.Abstract Spinal cord injury (SCI) is characterized by autonomic cardiovascular dysfunction that may contribute to the three‐ to fourfold greater risk of heart disease and stroke compared to non‐injured individuals. While exercise training elicits beneficial changes in autonomic function and vascular structure in healthy individuals, it is unclear if ...

Experimental Physiology, EarlyView.Abstract Cross‐adaptation occurs when exposure to one environmental stressor (e.g., heat) induces protective responses to another (e.g., hypoxia). Although post‐exercise hot‐water immersion (HWI) induces heat acclimation, its potential to elicit cross‐adaptation remains unclear.

Blood flow restriction exercise during microgravity exposure in parabolic flight
Experimental Physiology, EarlyView.Abstract This case report evaluates whether it is possible to perform blood flow restriction (BFR) exercise during exposure to microgravity. The objectives were three‐fold: (1) to determine if a personalised tourniquet system (PTS) hardware technology performs nominally and enables BFR exercise in microgravity; (2) to determine if BFR augments the ...

Cerebral haemodynamic responses to inspiratory muscle work
Experimental Physiology, EarlyView.Abstract Fatiguing inspiratory work has been shown to evoke a sympathetically mediated reflex that has systemic cardiovascular consequences, including increases in heart rate and blood pressure and a decrease in resting limb vascular conductance. Moreover, the response to this reflex appears to be attenuated in females compared with males.

Experimental Physiology, EarlyView.Abstract The aim of this study was to explore the primary afferent depolarization mechanism, to determine whether the soleus transspinal evoked potential (TEP), elicited through transcutaneous spinal cord stimulation over the L1–L2 level, is modulated by presynaptic inhibition and heteronymous facilitation, similar to the Hoffmann (H) reflex, elicited ...

Neuromotor changes in postural control following bed rest
The Journal of Physiology, EarlyView.Abstract figure legend Prolonged bed rest (BR) (both horizontal and head‐down tilt) leads to neuromotor adaptations that impair postural control. Structural and functional changes occur in the brain, including a reduction in grey and white matter volume, alterations in functional connectivity, and shifts in cerebrospinal fluid distribution.

Kv4 channels improve the temporal processing of auditory neurons in the cochlear nucleus
The Journal of Physiology, EarlyView.Abstract figure legend Kv4 channel improves temporal precision of auditory nerve‐evoked spikes in cochlear nucleus bushy neurons. Bushy neurons are specialized cells in processing information about temporal fine structure of sound critical for auditory tasks.
