摘要

当我们在空间中导航时,我们必须实时显示我们的位置;当回忆过去的一段往事时,一段记忆会在瞬间重现。有趣的是,大脑的空间表征系统,包括海马体,支持这两种不同的时间尺度功能。空间的神经表征是如何在现实世界的导航和内部助记过程中使用的?最近的进展已经确定了海马体位置细胞序列,根据导航行为或内部振荡在多个时间尺度上进化,这是这些功能的基础。我们回顾了这些顺序表征的经验依赖调制的实验结果,并考虑了它们如何将现实世界的导航与时间压缩记忆联系起来。我们进一步讨论了最近的研究表明这些序列在海马体之外的普遍存在,并提出这些多时间尺度机制可能代表了组织细胞组装的通用算法,可能统一空间表征系统在记忆和导航中的双重作用。

Multiple-Timescale Representations of Space: Linking Memory to Navigation.

Multiple-Timescale Representations of Space: Linking Memory to Navigation.

When navigating through space, we must maintain a representation of our position in real time; when recalling a past episode, a memory can come back in a flash. Interestingly, the brain's spatial representation system, including the hippocampus, supports these two distinct timescale functions. How are neural representations of space used in the service of both real-world navigation and internal mnemonic processes? Recent progress has identified sequences of hippocampal place cells, evolving at multiple timescales in accordance with either navigational behaviors or internal oscillations, that underlie these functions. We review experimental findings on experience-dependent modulation of these sequential representations and consider how they link real-world navigation to time-compressed memories. We further discuss recent work suggesting the prevalence of these sequences beyond hippocampus and propose that these multiple-timescale mechanisms may represent a general algorithm for organizing cell assemblies, potentially unifying the dual roles of the spatial representation system in memory and navigation.
