This study identifies electrophysiological correlates of lucid dreaming using EEG data from multiple labs, finding source-level changes in gamma1 and alpha power.

This paper introduces fractal cycles as a new definition of sleep cycles based on fractal neural activity, showing correlations with classical cycles and differences across age groups and depression states.

This study examines the effects of sustained polyphasic sleep restriction on human growth hormone release and other physiological and cognitive measures.

This study examines how slow-wave sleep and REM sleep affect plasma amyloid-beta levels, finding distinct associations with growth hormone, cortisol, and age-related clearance efficiency.

This study analyzes non-REM sleep EEG features in MDD patients and finds subtle alterations linked to medication and memory consolidation.

This study shows that mnemonic training improves durable memory formation by reducing task-based brain activation and enhancing consolidation.

The paper introduces composite EEG measures for NREM sleep based on power law scaling, reducing 191 metrics to four, and shows their utility in characterizing age, sex, and intelligence effects.

This study shows that detailed slow wave morphology, beyond standard parameters, is linked to age and cognitive decline, suggesting it as a biomarker for ageing.

This study confirms the link between 2D:4D ratio and spatial performance in rats and humans, and identifies brain correlates in humans.
