An update on pacemaking in the myometrium

The Journal of Physiology, EarlyView.
Abstract figure legend The spread of multiple electrical signals (panel A, blue‐to‐red indicates increasing electrical excitability) that are spatiotemporally distinct, yet in‐phase with the excitatory episode, determines action potential shape and form (panel B, as recorded by single cell microelectrodes) and ensures contractile amplitude and duration

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.

Gap junctional and ephaptic coupling in cardiac electrical propagation: homocellular and heterocellular perspectives

The Journal of Physiology, EarlyView.
Abstract figure legend Intricate cellular electrical coupling networks in the heart. Various cell types couple the central cardiomyocyte through gap junctional contacts, with the exception of neurons. Whether ephaptic coupling (EpC) occurs in homocellular or heterocellular contexts beyond cardiomyocyte–cardiomyocyte interactions remains unclear ...

Mechanisms underlying local Ca2+ signalling differences between right and left atrial myocytes at normal and increased frequencies

The Journal of Physiology, EarlyView.
Abstract figure legend Left atrial myocytes have TAT‐associated faster Ca2+ release but are more prone to maladaptation at higher frequencies due to weaker peripheral SR Ca2+ uptake and smaller trigger Ca2+ current. Abstract Changes in heart rate affect Ca2+ signalling and contractility in ventricular muscle, but the effects on atrial Ca2+ signalling ...
