Adaptive mediolateral control during split‐belt walking: Energetics of interlimb coordination and enhanced savings following acute intermittent hypoxia

Experimental Physiology, EarlyView.
Abstract Control of frontal plane mechanics requires active integration of sensory feedback to regulate stability in response to gait perturbations, such as split‐belt walking (SBW). In comparison to sagittal plane mechanics, mediolateral (ML) kinematic and kinetic adaptations to split‐belt perturbations are less extensively reported.

Pulmonary arterial mechanoreceptors mediate sustained sympathoexcitation during high altitude hypoxia in humans

Experimental Physiology, EarlyView.
Abstract Sympathetic nervous system activation is a hallmark of high‐altitude hypoxia, yet the afferent mechanisms remain incompletely defined. We examined the relative contributions of pulmonary arterial mechanoreceptors and carotid chemoreceptors – two excitatory pathways co‐activated by hypoxia – to sustained sympathoexcitation at altitude.

Pilot/vehicle model analysis of visual and motion cue requirements in flight simulation [PDF]

The optimal control model (OCM) of the human operator is used to predict the effect of simulator characteristics on pilot performance and workload. The piloting task studied is helicopter hover.

Virtual left atrial appendage occlusion in paroxysmal atrial fibrillation during sinus rhythm predicts variable reductions in blood stasis

The Journal of Physiology, EarlyView.
Abstract figure legend Stasis before and after left atrial appendage occlusion (LAAO) in participants with high stasis and low stasis. Stasis is predominantly located in LAA and reduced after LAAO. But in the participant with high stasis, stasis remains close to the occlusion site, indicating a potential risk for device related thrombi.

Effects of nocturnal periodic breathing on sympathetic nerve activity and ventilatory control at high altitude: a randomised, crossover study

The Journal of Physiology, EarlyView.
Abstract figure legend Schematic overview of the randomised crossover study investigating the effects of nocturnal periodic breathing (nPB) on sympathetic activity and ventilatory acclimatisation in hypobaric hypoxia equivalent to 4000 m altitude. Participants completed two 3‐day sojourns where nPB was inhibited by increasing inspiratory CO2 fraction ...

Lactate potentiates NMDA receptor currents via an intracellular redox mechanism targeting GluN2B subunits: implications for synaptic plasticity

The Journal of Physiology, EarlyView.
Abstract figure legend Astrocyte‐derived lactate enhances neuronal NMDA receptor (NMDAR) function and synaptic plasticity through a redox‐ and CaMKII‐dependent mechanism. Lactate enters neurons via monocarboxylate transporters (MCTs) and is oxidized by lactate dehydrogenase (LDH) to pyruvate, generating NADH and increasing the intracellular NADH/NAD ...
