Sodium Oxybate Alters Sleep Architecture and Reduces Emotional Selectivity in Memory‐Related Responses

Journal of Sleep Research, EarlyView.
ABSTRACT Sleep supports memory consolidation. Non‐rapid eye movement (NREM) and rapid eye movement (REM) sleep have been proposed to support, respectively, declarative memory consolidation and the integration of the memory affective dimension. Here, we used sodium oxybate (SXB) to modify the NREM/REM proportion during one sleep night and assessed ...

A Systematic Review and Meta‐Analysis of Biological Sex Differences in Sleep Spindles and Slow Wave Activity in Adults With and Without Insomnia

Journal of Sleep Research, EarlyView.
ABSTRACT Mounting evidence shows sex‐based differences in sleep experiences and outcomes, including the prevalence of insomnia disorder. However, the impact of biological sex on brain oscillations during sleep remains poorly understood, especially in the context of insomnia disorder. This is a notable gap, given that neurophysiological aspects of sleep

How Mental Concepts Shape Sleep: Introducing the Mental Concept Reactivation Hypothesis of Sleep

Journal of Sleep Research, EarlyView.
ABSTRACT Sleep problems affect a substantial proportion of individuals, and negative thoughts, rumination, and worry are considered key factors underlying persistence and severity. While extensive research has examined how these states disrupt sleep before falling asleep, much less is known about how mental concepts, including thoughts, expectations ...

Whole‐Night Gentle Rocking Improves Sleep in Poor Sleepers With Insomnia Complaints

Journal of Sleep Research, EarlyView.
ABSTRACT Specific brain oscillations can be manipulated during sleep to improve sleep quality and memory performance. We previously demonstrated that continuous rocking stimulation (0.25 Hz, lateral movement) applied to good sleepers during sleep enhanced stable deep sleep, boosted NREM oscillations (spindles and slow waves) and memory consolidation ...
