The hippocampus is essential for some types of memory, but its specific role remains conjectural. While studies on place cells have supported the hypothesis that the hippocampus provides a spatial substrate for episodic memory, recent engram studies have shown that optogenetic activation of a subset of hippocampal neurons that lack a temporal structure of the spike sequences can also induce memory-associated behavior. In this short review, I discuss the various lines of research that have led to different views of the role of the hippocampus in memory and propose a plausible interpretation of the findings that incorporates two influential theories.

海马体中的异质表征

海马体对于某些类型的记忆是必不可少的,但它的具体作用仍然是猜测。虽然对位置细胞的研究支持海马体为情景记忆提供空间基质的假设,但最近的印迹研究表明,缺乏尖峰序列时间结构的海马神经元子集的光遗传学激活也可以诱导记忆相关行为. 在这篇简短的评论中,我讨论了导致海马体在记忆中的作用的不同观点的各种研究方向,并提出了对包含两个有影响的理论的研究结果的合理解释。
