A perspective on automated rapid eye movement sleep assessment
Journal of Sleep Research, Volume 34, Issue 2, April 2025.Summary Rapid eye movement sleep is associated with distinct changes in various biomedical signals that can be easily captured during sleep, lending themselves to automated sleep staging using machine learning systems. Here, we provide a perspective on the critical characteristics of biomedical signals associated with rapid eye movement sleep and how ...

Journal of Sleep Research, EarlyView.Summary Nocturnal arrhythmia avalanche (NAA) episodes, characterised by transient non‐sustained cardiac arrhythmias during sleep, have been demonstrated as a predictor of adverse cardiovascular events. However, their dynamics and association with sleep architecture and events remain unclear.

Disorders of gut–brain interaction through the lens of polyvagal theory
Neurogastroenterology &Motility, Volume 37, Issue 3, March 2025.This paper introduces a metric, vagal efficiency (VE), that tracks a brainstem “switching” mechanism regulating blood pressure's effect on vagal control of the heart and gut. Potentially offering insights into gut–brain interaction disorders. Abstract This paper introduces a metric capable of tracking a hypothetical brainstem “switching” mechanism ...
