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.
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.
Auditory stimulation enhances oscillations linked to overnight memory processing and shows promise as a technique for enhancing the memory benefits of sleep.
听觉刺激是一种可增强与夜间记忆巩固相关的神经振荡的技术。在本综述中，我们评估了听觉刺激对各种人群睡眠神经振荡及相关记忆过程的影响。
慢波睡眠（SWS）的皮层脑电图记录具有两种主要振荡特征：慢振荡（SOs）和睡眠纺锤波。在SWS期间给予听觉刺激可增强健康儿童和成人、患有注意力缺陷多动障碍（ADHD）的儿童、患有轻度认知障碍的成人以及重度抑郁症患者的SOs和相位耦合纺锤波活动。在某些情况下，听觉刺激可增强SWS对记忆巩固的益处，不过还需要进一步研究以充分了解影响与刺激相关的记忆增强的因素。最近的研究已转向快速眼动（REM）睡眠，表明听觉刺激可用于操控REM睡眠θ振荡。
听觉刺激可增强与夜间记忆处理相关的振荡，并有望成为一种增强睡眠记忆益处的技术。
