Spectral validity and spindle detection of wearable frontal Electroencephalography: A per‐subject calibration framework and systematic validation against polysomnography using the Wearanize+ dataset

open access: yesSleep Research, EarlyView.
Abstract Background Wearable Electroencephalography (EEG) devices enable home sleep monitoring but require systematic spectral validation before their physiological outputs can serve as proxies for polysomnographic features. Aims This study provides comprehensive spectral validation of the Zmax EEG headband against concurrent polysomnography (PSG ...

Interrelations of slow and high frequency activity in the NREM sleep EEG in the rat

open access: yes, 2010
Introduction: Under constant sleep pressure, which can be achieved by repeated short-sleep deprivation, the marker of the sleep homeostat - slow wave activity (SWA, 1-4 Hz) in the NREM sleep electroencephalogram (EEG) - tends to stabilize its circadian ...

Oscillations of NREM sleep.

open access: yes, 2015
(A) Slow oscillation (SO) present throughout NREM sleep; (B) slow wave activity (SWA) characteristic of deep NREM sleep; (C) sleep spindles characteristic of light NREM sleep; and (D) sharp wave ripple (SWR) associated with the hippocampus and memory ...

Acoustic stimulation for sleep enhancement and declarative memory: A systematic review and meta‐analysis

open access: yesSleep Research, EarlyView.
Abstract Background Acoustic stimulation is a non‐invasive neuromodulation approach with unclear efficacy for sleep and cognition across paradigms and populations. This meta‐analysis systematically evaluated its effects on sleep architecture and declarative memory. Methods We searched the PubMed, Web of Science, the Cochrane Library, Scopus, and Embase

Pathophysiology of developmental and/or epileptic encephalopathy with spike–wave activation in sleep: A diagnostic framework

open access: yesDevelopmental Medicine &Child Neurology, EarlyView.
This review integrates emerging evidence on the pathophysiology of D/EE‐SWAS, highlighting the role of disrupted sleep homeostasis and thalamocortical network dysfunction. We propose a clinically applicable diagnostic framework that combines sleep EEG, structural imaging, genomic testing and longitudinal neuropsychological assessment to improve ...

Associations between the apnea-hypopnea index during REM and NREM sleep and cognitive functioning in a cohort of middle-aged adults

open access: yes, 2019
Study Objectives Prior research has linked obstructive sleep apnea (OSA) to varied cognitive deficits. Additionally, OSA in rapid eye movement (REM) versus non-rapid eye movement (NREM) sleep has been shown to be a stronger predictor of outcomes such as

A perspective on automated rapid eye movement sleep assessment

open access: yesJournal 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 ...

Re-defining discontinuity: Implications for the functions of dreaming [PDF]

open access: yes, 2011
Hobson and Schredl’s dialogue (2011) raised important questions concerning the operationalisation of continuity across sleep and wake, especially in contrast to discontinuity, and questioned the potential functionality of such continuity.

Neurobehavioral Associations with NREM and REM Sleep Architecture in Children with Autism Spectrum Disorder

open access: yes, 2022
Objective: Insomnia and daytime behavioral problems are common issues in pediatric autism spectrum disorder (ASD), yet specific underlying relationships with NonRapid Eye Movement sleep (NREM) and Rapid Eye Movement (REM) sleep architecture are ...
