模拟海马体与皮层记忆系统的认知模型，揭示记忆如何形成与受损。
Cognitive algorithms and systems of episodic memory, semantic memory and their learnings
- 基于海马体与皮层结构构建计算系统，模仿显性记忆机制
- 成功复现顺行性、逆行性和发育性遗忘症等记忆缺陷
- 适合研究记忆神经机制或类脑智能的学者参考
陈述性记忆由可被语言表达的两部分组成：情景记忆和语义记忆。这种分离具有神经解剖学基础——情景记忆主要关联海马体，语义记忆则与新皮层相关。尽管如此，两者仍密切相关。海马体损伤常导致多种显性记忆障碍，如顺行性遗忘、逆行性遗忘及发育性失忆，并伴随语义学习缺陷。这些症状为理解两种记忆的获取、存储与组织机制提供了契机。本文综述了多个以显性记忆为核心的认知系统，以及基于神经解剖结构、用于模拟上述记忆障碍的计算系统。内容涵盖系统结构、学习规则及其对记忆获取与损伤的仿真表现。
原文摘要 · Abstract (English)
Declarative memory, the memory that can be "declared" in words or languages, is made up of two dissociated parts: episodic memory and semantic memory. This dissociation has its neuroanatomical basis episodic memory is mostly associated with the hippocampus and semantic memory with the neocortex. The two memories, on the other hand, are closely related. Lesions in the hippocampus often result in various impairments of explicit memory, e.g., anterograde, retrograde and developmental amnesias, and semantic learning deficit. These impairments provide opportunities for us to understand how the two memories may be acquired, stored and organized. This chapter reviews several cognitive systems that are centered to mimic explicit memory, and other systems that are neuroanatomically based and are implemented to simulate those memory impairments mentioned above. This review includes: the structures of the computational systems, their learning rules, and their simulations of memory acquisition and impairments.
