陈述性记忆是我们所谓的日常语言记忆，我们能够通过记忆行为描述或明确体验。这种有意识的回忆使我们能够根据我们以前的经验（情景记忆）和知识（语义记忆）来思考未来。内侧颞叶（MTL）是一个分层组织的复合体，其中嗅周皮层和海马旁皮层通过内嗅皮层向海马提供项目和上下文信息，海马在联想和回忆中起主要作用。这种传统观点为声明性存储器系统提供了容易理解的结构。然而，报道单个神经元活动的神经生理学研究带来了更复杂的观点。在这篇文章中，我回顾了单单位的研究，特别是那些集中在嗅周皮层和海马，并建议陈述性记忆的关联过程中，更多地分布在MTL地区。嗅周皮层代表了两个域之间的关联（例如，项目-奖励、项目-地点和项目-时间）和域内关联（例如，项目项目）并对陈述性记忆的两个子类别都有贡献（即，情景记忆和语义记忆）与海马体互补。(C)2016爱思唯尔爱尔兰有限公司和日本神经科学学会。All rights reserved.
Declarative memories are our so-called daily language memories, which we are able to describe or explicitly experience through the act of remembering. This conscious recollection makes it possible for us to think about the future based on our previous experience (episodic memory) and knowledge (semantic memory). This cognitive function is substantiated by the medial temporal lobe (MTL), a hierarchically organized complex in which the perirhinal cortex and parahippocampal cortex provide item and context information to the hippocampus via the entorhinal cortex, and the hippocampus plays the main role in association and recollection. This conventional view provides an easily understood structure to the declarative memory system. However, neurophysiological studies reporting the activities of single neurons bring a more complicated view. In this article, I review single-unit studies, particularly those focused on the perirhinal cortex and hippocampus, and suggest that association processes for declarative memory are more distributed over the MTL areas. The perirhinal cortex represents both between-domain associations (e.g., item-reward, item-place and item-time) and within-domain associations (e.g., item item) and contributes to both subcategories of declarative memory (i.e., episodic and semantic memory) in a way that is complementary with the hippocampus.
