Numerous studies have explored the effect of sleep on memory. It is well known that a period of sleep, compared to a similar period of wakefulness, protects memories from interference, improves performance, and might also reorganize memory traces in a way that encourages creativity and rule extraction. It is assumed that these benefits come from the reactivation of brain networks, mainly involving the hippocampal structure, as well as from their synchronization with neocortical networks during sleep, thereby underpinning sleep-dependent memory consolidation and reorganization. However, this memory reorganization is difficult to explain within classical memory models. The present paper aims to describe whether the influence of sleep on memory could be explained using a multiple trace memory model that is consistent with the concept of embodied cognition: the Act-In (activation-integration) memory model. We propose an original approach to the results observed in sleep research on the basis of two simple mechanisms, namely activation and integration.
大量研究探讨了睡眠对记忆的影响。众所周知，与相似的清醒时间相比，睡眠可以保护记忆免受干扰，提高表现，还可能以一种促进创造力和规则提取的方式重新组织记忆痕迹。人们认为，这些好处来自于大脑网络的重新激活，主要涉及海马体结构，以及在睡眠期间与新皮层网络的同步，从而支持睡眠依赖的记忆巩固和重组。然而，这种记忆重组在经典记忆模型中很难解释。本文旨在描述睡眠对记忆的影响是否可以使用与具身认知概念一致的多重痕迹记忆模型来解释：激活-整合（Activation-Integration）记忆模型。我们基于激活和整合这两个简单的机制，提出了一种对睡眠研究中观察到的结果的新颖解释方法。
