This paper explores memory from a cognitive neuroscience perspective and examines associated neural mechanisms. It examines the different types of memory: working, declarative, and non-declarative, and the brain regions involved in each type. The paper highlights the role of different brain regions, such as the prefrontal cortex in working memory and the hippocampus in declarative memory. The paper also examines the mechanisms that underlie the formation and consolidation of memory, including the importance of sleep in the consolidation of memory and the role of the hippocampus in linking new memories to existing cognitive schemata. The paper highlights two types of memory consolidation processes: cellular consolidation and system consolidation. Cellular consolidation is the process of stabilizing information by strengthening synaptic connections. System consolidation models suggest that memories are initially stored in the hippocampus and are gradually consolidated into the neocortex over time. The consolidation process involves a hippocampal-neocortical binding process incorporating newly acquired information into existing cognitive schemata. The paper highlights the role of the medial temporal lobe and its involvement in autobiographical memory. Further, the paper discusses the relationship between episodic and semantic memory and the role of the hippocampus. Finally, the paper underscores the need for further research into the neurobiological mechanisms underlying non-declarative memory, particularly conditioning. Overall, the paper provides a comprehensive overview from a cognitive neuroscience perspective of the different processes involved in memory consolidation of different types of memory.
本文从认知神经科学的角度探讨记忆，并研究相关的神经机制。它考察了不同类型的记忆：工作记忆、陈述性记忆和非陈述性记忆，以及每种类型所涉及的脑区。本文强调了不同脑区的作用，如前额叶皮质在工作记忆中的作用以及海马体在陈述性记忆中的作用。本文还研究了记忆形成和巩固的潜在机制，包括睡眠在记忆巩固中的重要性以及海马体在将新记忆与现有认知图式联系起来方面的作用。本文强调了两种记忆巩固过程：细胞巩固和系统巩固。细胞巩固是通过加强突触连接来稳定信息的过程。系统巩固模型表明，记忆最初存储在海马体中，并随着时间的推移逐渐巩固到新皮质中。巩固过程涉及一个海马体 - 新皮质绑定过程，即将新获取的信息纳入现有的认知图式。本文强调了内侧颞叶的作用及其在自传体记忆中的参与。此外，本文讨论了情景记忆和语义记忆之间的关系以及海马体的作用。最后，本文强调需要进一步研究非陈述性记忆，特别是条件作用背后的神经生物学机制。总体而言，本文从认知神经科学的角度全面概述了不同类型记忆巩固中涉及的不同过程。
