Abstract

Tags are attached to salient information during the wake period, which can preferentially determine what information can be consolidated during sleep. Previous studies demonstrated that spindles during non-rapid eye movement (NREM) sleep give priority to strengthening memory representations with tags, indicating a privileged reactivation of tagged information. The current meta-analysis investigated whether and how spindles can capture different tags to consolidate declarative memory. This study searched the Web of Science, Google Scholar, PubMed, PsycINFO, and OATD databases for studies that spindles consolidate declarative memory with tags. A meta-analysis using a random-effects model was performed. Based on 19 datasets from 18 studies (N = 388), spindles had a medium effect on the consolidation of declarative memory with tags ( r = 0.519). In addition, spindles derived from whole-night sleep and nap studies were positively related to the consolidation of memory representations with tags. These findings reveal the shared mechanism that spindles are actively involved in the prefrontal-hippocampus circuits to consolidate memory with tags.

睡眠主轴巩固带有标签的陈述性记忆：成人数据荟萃分析

唤醒期的突出信息会被贴上标签，这可以优先决定哪些信息可以在睡眠期得到巩固。之前的研究表明，非快速眼动睡眠（NREM）期间的主轴会优先强化带有标签的记忆表征，这表明标签信息具有优先重新激活的特性。目前的荟萃分析调查了主旋是否以及如何捕捉不同的标签来巩固陈述性记忆。本研究在 Web of Science、Google Scholar、PubMed、PsycINFO 和 OATD 数据库中搜索了有关主轴通过标签巩固陈述性记忆的研究。采用随机效应模型进行了荟萃分析。根据来自 18 项研究的 19 个数据集（N = 388），主轴对带有标记的陈述性记忆的巩固有中等程度的影响（r = 0.519）。此外，来自整夜睡眠和小睡研究的主轴与带有标记的记忆表征的巩固呈正相关。这些发现揭示了主轴积极参与前额叶-海马环路巩固标记记忆的共同机制。

期刊介绍： ACS Applied Bio Materials is an interdisciplinary journal publishing original research covering all aspects of biomaterials and biointerfaces including and beyond the traditional biosensing, biomedical and therapeutic applications. The journal is devoted to reports of new and original experimental and theoretical research of an applied nature that integrates knowledge in the areas of materials, engineering, physics, bioscience, and chemistry into important bio applications. The journal is specifically interested in work that addresses the relationship between structure and function and assesses the stability and degradation of materials under relevant environmental and biological conditions.
