This study uses hippocampal stimulation during sleep to investigate memory consolidation, finding that timed stimulation improves memory retention and alters sleep oscillatory dynamics.

This study shows that thalamic temporal interference stimulation with a 5Hz envelope increases sleep spindle density through subthreshold resonance in thalamocortical relay neurons.

The paper examines how insufficient sleep affects tonic REM sleep EEG components and their associations with mood, cognition, and cortical excitability.

This study examines how variations in sleep within and between older adults relate to cognitive performance, finding that sleep duration and efficiency affect reaction time but not other cognitive functions.

This paper introduces a clinical-grade neurostimulation implant that adapts its therapy based on time-of-day to improve closed-loop treatment of neurological disorders.

This study examines how sleep and circadian rhythms affect brain functional connectivity and cognitive performance in humans using a forced-desynchrony protocol.

This study evaluates blood-based circadian biomarkers, showing that training data and protocols significantly affect performance, with feature selection methods playing a secondary role.

This study shows that closed-loop auditory stimulation can induce lateralised alpha frequency modulation in visual cortices during memory retention, linked to task performance asymmetry.

The paper mathematically extends the two-process model of sleep regulation to include light effects, enabling quantitative predictions of sleep and circadian interventions.

This study shows that closed-loop auditory stimulation can modulate alpha and theta oscillations during REM sleep in a phase-dependent manner, altering power and frequency.

The paper develops a model to integrate circadian and sleep-wake influences on gene expression, revealing tissue-specific regulatory effects and desynchronization after sleep deprivation.

This study uses multi-night recordings to show that Parkinson's disease affects NREM sleep by altering cortico-basal slow wave activity and subcortical beta power, with DBS enhancing these changes and predicting spontaneous awakenings.

This paper presents a mathematical analysis of light-sensitivity challenges in assessing the human circadian pacemaker's intrinsic period, showing that dim light may affect results more than previously thought.

This paper introduces a model to distinguish between endogenous and exogenous factors affecting sleep timing using longitudinal data and personalized mathematical modeling.

The paper investigates the association between brainstem myelin content and sleep parameters in healthy young men, finding significant links between myelin integrity and sleep quality metrics.

This paper introduces Alpha Closed-Loop Auditory Stimulation (CLAS) to modulate alpha oscillations and sleep onset dynamics in humans, showing phase-dependent effects on alpha power, frequency, and connectivity.

The paper compares rhythmic gene expression in human blood and baboon tissues/organs, finding overlapping and tissue-specific rhythmic genes with similar timing across species.

The paper compares two fatigue risk models, HSE Fatigue Risk tool and SAFTE, using data from a construction project, finding they give similar predictions but SAFTE better captures fatigue development during shifts.

This study identifies REM sleep as a core response to chronic stress in mice, linking it to corticosterone regulation and apoptotic pathways through transcriptomic analysis.
