A comparison of the neuromuscular, cardiopulmonary and muscle oxygenation responses to single‐ and double‐leg cycling in older adults

open access: yesExperimental Physiology, EarlyView.
Abstract Previous work in younger adults has shown that during small muscle mass exercise, the tolerable degree of neuromuscular impairment at task failure is greater than during large muscle mass exercise. However, no study has compared the neuromuscular responses to small and large muscle mass exercise whilst matching exercise modality in older ...

Stretch versus shortening contractions subsequently decrease versus increase neural drive to the human tibialis anterior

open access: yesExperimental Physiology, EarlyView.
Abstract EMG‐based muscle force predictions are often inaccurate following active muscle stretch or shortening because of residual force enhancement (rFE) or depression (rFD), respectively, which can alter the neural drive to a muscle. However, the extent of neural drive modulation attributable to rFE or rFD remains unknown owing to the limited spatial

Electrodiffusion in cardiac intercalated disc nanostructures alters cell–cell action potential transmission via ephaptic coupling: A model study

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Ephaptic phenomena in a high‐resolution model of the cardiac intercalated disc. Meshed representation of a tortuous intercalated disc that was generated based on electron and super‐resolution microscopy data. Na+ channels (red) and gap junctions (green) are heterogeneously distributed, with additional regions of reduced ion ...

High‐throughput, high‐fidelity reconstruction of whole mouse‐heart cytoarchitecture at cellular scale

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Experimental workflow of the dual‐camera light‐sheet microscope (dual‐mesoSPIM) pipeline. Intact adult mouse hearts undergo CUBIC‐based delipidation and refractive‐index matching, rendering the whole organ optically transparent (left).

Low‐threshold cutaneous mechanoreceptors on the foot sole have enhanced sensitivity when skin temperature is elevated

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Schematic illustration of microneurography recordings used to examine the effects of local skin heating on cutaneous mechanoreceptor responses in the human foot (left panel). A microelectrode inserted into a peripheral nerve records single‐unit activity from tactile afferent fibres while controlled mechanical stimuli are applied ...
