Sleep and cardiac autonomic modulation in older adults: Insights from an at‐home study with auditory deep sleep stimulation

Journal of Sleep Research, Volume 34, Issue 2, April 2025.
Summary The autonomic nervous system regulates cardiovascular activity during sleep, likely impacting cardiovascular health. Aging, a primary cardiovascular risk factor, is associated with cardiac autonomic disbalance and diminished sleep slow waves. Therefore, slow waves may be linked to aging, autonomic activity and cardiovascular health. However, it

Validation of OSLER Test Against Maintenance of Wakefulness Test and the Association With Subjective Measures of Sleepiness

Journal of Sleep Research, EarlyView.
ABSTRACT The ability to stay awake is crucial in life and can be compromised by insufficient sleep and medical conditions. Measuring alertness is important for evaluating driving ability and the Oxford Sleep Resistance (OSLER) test may provide an easy way for assessment.

Optimising Sleep Stage Detection Using a Minimal Non‐EEG Physiological Signal Set and Deep Learning

Journal of Sleep Research, EarlyView.
ABSTRACT Automatic sleep stage classification is essential for enabling non‐invasive, at‐home monitoring. However, current methods often rely on electroencephalogram (EEG) signals and ad‐hoc development approaches that limit reproducibility. We present a reproducible engineering framework for a deep learning model based on the U‐Net architecture that ...

Electromyography Frequency Spectrum Is a Better Indicator of Sleep Bruxism Severity Related to Temporomandibular Disorder Pain Than Conventional Masticatory Muscle Activation and Bruxism Time Indices—A Pilot Study

Journal of Sleep Research, EarlyView.
ABSTRACT Sleep bruxism (SB) has been reportedly associated with temporomandibular disorder (TMD); however, solid evidence is lacking. Previous studies have primarily used traditional metrics, such as the masticatory muscle activity (MMA) index and bruxism time index (BTI) to investigate the link between SB and TMD.

Refining Detection of Subclinical Epileptiform Activity in Alzheimer's Disease: A Case–Control Study and Call for a Consensus

Annals of Neurology, Volume 99, Issue 4, Page 1046-1058, April 2026.
[Color figure can be viewed at www.annalsofneurology.org] Objective Sleep‐predominant network hyperexcitability is increasingly recognized as a potential disease‐accelerating comorbidity in Alzheimer's disease (AD). However, its prevalence and risk‐factors remain debated, largely due to cohort‐specific and methodological differences across studies.

Distinct Resting‐State Connectomes for Face and Scene Perception Predict Individual Task Performance

Human Brain Mapping, Volume 47, Issue 5, 1 April 2026.
Resting‐state fMRI and MEG functional connectivity reveal that the FFA and PPA anchor distinct spatio‐temporal networks. The strength of this intrinsic architecture shows a double dissociation: FFA‐network connectivity specifically predicts face‐task performance, while PPA‐network connectivity predicts scene‐task performance, linking intrinsic ...

Hybrid System for Engagement Recognition During Cognitive Tasks Using a CFS + KNN Algorithm

Sensors, 2018
Engagement is described as a state in which an individual involved in an activity can ignore other influences. The engagement level is important to obtaining good performance especially under study conditions. Numerous methods using electroencephalograph
