[Research progress on the relationship between neural synchronization activity and memory consolidation during non-rapid eye movement sleep].

Neural synchronization activity is considered a key aspect of information processing in the nervous system. Local synchronization within different frequency ranges and inter-regional synchronization are ubiquitous and related to various behavioral and cognitive functions. As memory is a higher cognitive function of the brain, the formation and consolidation of memory are closely related to neural synchronization activity. This article provides an overview of the research progress on the relationship between neural synchronization activity and memory consolidation, focusing primarily on the neuro-oscillatory activities across multiple brain regions during non-rapid eye movement (NREM) sleep in vivo, as well as the synchronous burst activity in cultured neural networks in vitro. Finally, we analyzed the existing issues in current research and provided a perspective on future relevant studies.
