Abstract

Purpose of review: Auditory stimulation is a technique that can enhance neural oscillations linked to overnight memory consolidation. In this review, we evaluate the impacts of auditory stimulation on the neural oscillations of sleep and associated memory processes in a variety of populations.

Recent findings: Cortical EEG recordings of slow-wave sleep (SWS) are characterised by two cardinal oscillations: slow oscillations (SOs) and sleep spindles. Auditory stimulation delivered in SWS enhances SOs and phase-coupled spindle activity in healthy children and adults, children with ADHD, adults with mild cognitive impairment and patients with major depression. Under certain conditions, auditory stimulation bolsters the benefits of SWS for memory consolidation, although further work is required to fully understand the factors affecting stimulation-related memory gains. Recent work has turned to rapid eye movement (REM) sleep, demonstrating that auditory stimulation can be used to manipulate REM sleep theta oscillations.

Summary: Auditory stimulation enhances oscillations linked to overnight memory processing and shows promise as a technique for enhancing the memory benefits of sleep.

发声:听觉刺激和夜间记忆处理。

复习目的:听觉刺激是一种可以增强与夜间记忆巩固相关的神经振荡的技术。在这篇综述中，我们评估了听觉刺激对不同人群睡眠和相关记忆过程的神经振荡的影响。最近的研究发现:慢波睡眠(SWS)的皮质脑电图记录以两种基本振荡为特征:慢波振荡(so)和睡眠纺锤波。在健康儿童和成人、ADHD儿童、轻度认知障碍成人和重度抑郁症患者中，在SWS中传递的听觉刺激增强了SOs和相耦合纺锤体活动。在某些条件下，听觉刺激增强了SWS对记忆巩固的好处，尽管需要进一步的工作来充分了解影响刺激相关记忆增益的因素。最近的研究转向了快速眼动(REM)睡眠，表明听觉刺激可以用来操纵快速眼动睡眠的θ波振荡。总结:听觉刺激增强了与夜间记忆处理相关的振荡，有望成为一种增强睡眠对记忆的好处的技术。

期刊介绍： Current Sleep Medicine Reports aims to review the most important, recently published articles in the field of sleep medicine. By providing clear, insightful, balanced contributions by international experts, the journal intends to serve all those involved in the care and prevention of sleep conditions. We accomplish this aim by appointing international authorities to serve as Section Editors in key subject areas such as insomnia, narcolepsy, sleep apnea, circadian rhythm disorders, and parasomnias. Section Editors, in turn, select topics for which leading experts contribute comprehensive review articles that emphasize new developments and recently published papers of major importance, highlighted by annotated reference lists. An international Editorial Board reviews the annual table of contents, suggests articles of special interest to their country/region, and ensures that topics are current and include emerging research. Commentaries from well-known figures in the field are also occasionally provided.
