ABSTRACT

This special issue of Cognitive Neuroscience focuses on the roles of the hippocampus during long-term memory. A discussion paper by Tallman, Clark, and Smith (this issue) found that functional connectivity of the hippocampus with the parahippocampal cortex and fusiform gyrus decreased with memory age, providing support for systems consolidation. Commentaries were received by Berdugo-Vega and Gräff (this issue), Feld and Gerchen (this issue), Gellersen and Simons (this issue), Gobbo, Mitchell-Heggs, and Tse (this issue), Gilmore, Audrain, and Martin (this issue), Kirwan (this issue), Manns (this issue), Runyan and Brooks (this issue), Santangelo (this issue), and Yang (this issue). The author response considered the content and context of memorial information along with neuroanatomy and functional specialization and conducted new analyses to clarify their findings. An empirical fMRI paper by Thakral, Yu, and Rugg (this issue) reported that the hippocampus was sensitive to the amount of contextual information retrieved, regardless of remember-know status. Another empirical study by Bjornn, Van, and Kirwan (this issue) found that hippocampal activation changes were correlated with the number of fixations at study for correct but not incorrect mnemonic discrimination judgments. A second discussion paper (Slotnick, this issue) concluded that no fMRI studies have provided evidence that the hippocampus is associated with working memory. Commentaries were received by Courtney (this issue), Kessels and Bergmann (this issue), Peters and Reithler (this issue), Rose and Chao (this issue), Stern and Hasselmo (this issue), and Wood, Clark, and Nee (this issue). The articles in this special issue illustrate that the roles of the hippocampus in long-term memory (and other types of memory) are under active investigation and provide many directions for research in the immediate future.

摘要

本期认知神经科学特刊侧重于海马体在长期记忆中的作用。Tallman、Clark 和 Smith 的一篇讨论文件（本期）发现，海马体与海马旁皮质和梭状回的功能连通性随着记忆年龄的增长而降低，为系统整合提供了支持。Berdugo-Vega 和 Gräff（本期）、Feld 和 Gerchen（本期）、Gellersen 和 Simons（本期）、Gobbo、Mitchell-Heggs 和 Tse（本期）、Gilmore、Audrain 和 Martin（本期）收到了评论。本期）、Kirwan（本期）、Manns（本期）、Runyan 和 Brooks（本期）、Santangelo（本期）和 Yang（本期）。作者的回应考虑了纪念信息的内容和背景以及神经解剖学和功能专业化，并进行了新的分析以阐明他们的发现。Thakral、Yu 和 Rugg 的一篇经验性 fMRI 论文（本期）报告说，海马体对检索到的上下文信息量很敏感，无论记忆-已知状态如何。Bjornn、Van 和 Kirwan 的另一项实证研究（本期）发现，海马体激活变化与研究中的注视次数相关，以做出正确而非错误的记忆辨别判断。第二篇讨论文件（Slotnick，本期）得出结论，没有 fMRI 研究提供证据表明海马体与工作记忆相关。Courtney（本期）、Kessels 和 Bergmann（本期）、Peters 和 Reithler（本期）、Rose 和 Chao（本期）、Stern 和 Hasselmo（本期）以及 Wood、Clark 和 Nee（本期）收到了评论这个问题）。
