Firing properties of muscle spindle afferents in the intrinsic foot muscles and tactile afferents from the sole of the foot during upright stance

open access: yesExperimental Physiology, EarlyView.
Abstract We review our approach for undertaking microelectrode recordings from the posterior tibial nerve at the ankle, which has allowed us to identify, for the first time, the firing properties of muscle spindle endings in the intrinsic muscles of the foot and of cutaneous mechanoreceptors in the sole during unsupported standing.

Optogenetic methods to stimulate gamma motor neuron axons ex vivo

open access: yesExperimental Physiology, EarlyView.
Abstract It is challenging to stimulate gamma motor neurons, which are important regulators of muscle spindle afferent function, without also recruiting alpha motor neurons. Here, we test the feasibility of stimulating gamma motor neuron axons using optogenetics in two transgenic mouse lines. We used an ex vivo muscle–nerve preparation in adult mice to

Differential intestinal injury and unchanged systemic inflammatory responses to leg and whole‐body passive hyperthermia in healthy humans

open access: yesExperimental Physiology, EarlyView.
Abstract Hyperthermia can cause intestinal injury, facilitating endotoxin translocation and an inflammatory response that has been associated with heat illness. However, the potential occurrence of these responses has been incompletely reported during passive hyperthermia, and the independent effect of hyperthermia is equivocal.

Calcium regulation of muscle spindle mechanosensory afferent function

open access: yesExperimental Physiology, EarlyView.
Abstract Extracellular calcium is crucial for the normal function of muscle spindle sensory afferents. They express multiple calcium buffering proteins. Extracellular calcium is essential for recycling of synaptic‐like vesicles (SLVs) in the terminals and for the stretch‐evoked inward calcium current of the receptor potential.
