Beyond Aging, Sex and Insomnia Disorder Shape NREM Brain Oscillations

This study examines how sex and insomnia affect NREM brain oscillations beyond aging, finding sex-specific differences in sleep markers that may explain higher insomnia prevalence in females.

A Systematic Review and Meta-Analysis of Biological Sex Differences in Sleep Spindles and Slow Wave Activity in Adults with and without Insomnia

This paper reviews and meta-analyzes studies on sex differences in sleep spindles and slow wave activity in adults with and without insomnia, finding sex-based variations in spindle density and power but limited interaction effects.

Whole-night gentle rocking improves sleep in poor sleepers with insomnia complaints.

This study shows that whole-night gentle rocking improves sleep quality and efficiency in individuals with insomnia complaints.

Sleep deprivation constrains dynamic configurations of integrated and segregated brain states impacting cognitive performance

This study shows sleep deprivation reduces brain network flexibility by altering thalamic regulation and coupling with cortical networks, leading to cognitive impairments.

EEG source imaging technique to investigate sleep oscillations for simultaneous EEG-fMRI

This paper applies beamforming spatial filtering to EEG-fMRI data to improve detection of sleep spindles and enhance fMRI GLM analysis by reducing BCG artefacts.

NREM sleep brain networks modulate cognitive recovery from sleep deprivation

The paper investigates how NREM sleep stages N2 and N3 modulate cognitive recovery after sleep deprivation by analyzing brain network segregation using fMRI and a new hierarchical segregation index.

A multidimensional investigation of sleep and biopsychosocial profiles with associated neural signatures

This study identifies sleep-biopsychosocial profiles in healthy adults by linking sleep patterns to health, cognition, and lifestyle factors, revealing distinct brain network organization patterns.

Phase-amplitude coupling of NREM sleep oscillations is unaffected by pre-sleep learning but related to overnight memory gains depending on the declarative learning paradigm

This study finds that phase-amplitude coupling between spindles and slow oscillations during NREM sleep is stable and not affected by pre-sleep learning, but correlates with memory consolidation in a specific learning paradigm.

Data-driven beamforming techniques to attenuate ballistocardiogram (BCG) artefacts in EEG-fMRI without detecting cardiac pulses in electrocardiography (ECG) recordings

This paper introduces a data-driven beamforming technique to reduce BCG artefacts in EEG-fMRI without using ECG signals, improving signal recovery for task-based neural activity.

An altered balance of integrated and segregated brain activity is a marker of cognitive deficits following sleep deprivation

This study shows that sleep deprivation alters the balance of cortical network integration and segregation, which correlates with cognitive deficits and recovery after a nap.
