我们假设一个有益的影响，睡眠对巩固的组合机制的增量句子理解。这些预测是基于最近的研究工作，研究睡眠对巩固语言信息的影响，这表明睡眠依赖的神经生理活动巩固了新单词和简单语法规则的含义。然而，睡眠依赖性巩固的双水平组合尚未研究到目前为止。在这里，我们提出，睡眠神经生理学的可分离方面巩固了人类语言中两种不同类型的组合机制：基于序列（顺序敏感）和基于依赖性（顺序不敏感）的组合。这两种类型的组合数学之间的区别是由跨语言的考虑和人类语言的神经生物学基础的动机。将这种观点与睡眠依赖性记忆巩固的原则相结合，我们认为睡眠的功能是优化基于序列的知识（时间）的巩固和无序项目（什么）的语义图式的建立，这些语义图式是句子理解中跨语言变化的基础。这一假说建立在睡眠参与构建预测代码的基础上，预测代码是支持渐进式句子理解的大脑功能的统一原则。最后，我们讨论了神经生理学的措施（EEG/ MEG），可用于测试这些索赔，如量化的神经元振荡，这反映了在大脑中的信息处理的基本机制。
We hypothesize a beneficial influence of sleep on the consolidation of the combinatorial mechanisms underlying incremental sentence comprehension. These predictions are grounded in recent work examining the effect of sleep on the consolidation of linguistic information, which demonstrate that sleep-dependent neurophysiological activity consolidates the meaning of novel words and simple grammatical rules. However, the sleep-dependent consolidation of sentence-level combinatorics has not been studied to date. Here, we propose that dissociable aspects of sleep neurophysiology consolidate two different types of combinatory mechanisms in human language: sequence-based (order-sensitive) and dependency-based (order-insensitive) combinatorics. The distinction between the two types of combinatorics is motivated both by cross-linguistic considerations and the neurobiological underpinnings of human language. Unifying this perspective with principles of sleep-dependent memory consolidation, we posit that a function of sleep is to optimize the consolidation of sequence-based knowledge (the when) and the establishment of semantic schemas of unordered items (the what) that underpin cross-linguistic variations in sentence comprehension. This hypothesis builds on the proposal that sleep is involved in the construction of predictive codes, a unified principle of brain function that supports incremental sentence comprehension. Finally, we discuss neurophysiological measures (EEG/ MEG) that could be used to test these claims, such as the quantification of neuronal oscillations, which reflect basic mechanisms of information processing in the brain.
