Sleep stages antagonistically modulate reactivation drift [PDF]
Neuron, 2023 AbstractHippocampal reactivation of waking neuronal assemblies in sleep is a key initial step of systems consolidation. Nevertheless, it is unclear whether reactivated assemblies are static or whether they reorganize gradually over prolonged sleep. Here, we tracked reactivated CA1 assembly patterns over ∼20 hours of sleep/rest periods and related them ...

Estimating Sleep Stages Using a Head Acceleration Sensor [PDF]
Sensors, 2021 Sleep disruption from causes, such as changes in lifestyle, stress from aging, family issues, or life pressures are a growing phenomenon that can lead to serious health problems. As such, sleep disorders need to be identified and addressed early on.

Scale-free and oscillatory spectral measures of sleep stages in humans [PDF]
Frontiers in Neuroinformatics, 2022 Power spectra of sleep electroencephalograms (EEG) comprise two main components: a decaying power-law corresponding to the aperiodic neural background activity, and spectral peaks present due to neural oscillations.

U-Sleep: resilient high-frequency sleep staging [PDF]
npj Digital Medicine, 2021 AbstractSleep disorders affect a large portion of the global population and are strong predictors of morbidity and all-cause mortality. Sleep staging segments a period of sleep into a sequence of phases providing the basis for most clinical decisions in sleep medicine.

Sleep CLIP: A Multimodal Sleep Staging Model Based on Sleep Signals and Sleep Staging Labels
Sensors, 2023 Since the release of the contrastive language-image pre-training (CLIP) model designed by the OpenAI team, it has been applied in several fields owing to its high accuracy. Sleep staging is an important method of diagnosing sleep disorders, and the completion of sleep staging tasks with high accuracy has always remained the main goal of sleep staging ...
