This study links noradrenergic infraslow rhythms during sleep to heart rate variability and memory consolidation across species.

This study investigates how heart rate variability during REM sleep influences emotional memory consolidation, finding that REM vagal HRV promotes a positive memory bias.

This paper develops a predictive model for sleep slow oscillation (SO) occurrences during NREM sleep, enabling more precise targeting for brain stimulation by analyzing SO timing and decay patterns across sleep cycles.

This study investigates how slow oscillations during sleep modulate working memory-related neural activity changes overnight.

This paper introduces a classification-based generative approach to optimize closed-loop tACS during sleep by targeting global slow oscillations, showing potential for improving memory consolidation.

The paper shows that slow oscillations during NREM sleep enhance long-range neural communication, which supports memory consolidation despite reduced overall connectivity.

This study examines age-related differences in autonomic-central coupling during daytime sleep and its impact on working memory in older versus younger adults.

The paper shows sleep involves competition between long-term and working memory processes, with a switch mechanism affecting cognitive performance.

The paper investigates slow oscillations during sleep, showing they enable long-range neural communication and support memory consolidation.

This study shows that increased parasympathetic activity during sleep improves working memory in young adults, unlike during wake.

This study shows that coordinated autonomic and central events during sleep predict working memory improvement in young adults.

The paper shows that during rest, the human hippocampus replays weakly-learned memories more, which predicts better memory performance and relates to memory improvement after sleep.

The paper identifies coordinated autonomic and central events during NREM sleep that predict declarative memory consolidation.

This study shows sleep enhances memory for shared category properties while preserving unique exemplar information, with effects influenced by REM and non-REM sleep.
