Since the first place cell was recorded and the cognitive-map theory was subsequently formulated, investigation of spatial representation in the hippocampal formation has evolved in stages. Early studies sought to verify the spatial nature of place cell activity and determine its sensory origin. A new epoch started with the discovery of head direction cells and the realization of the importance of angular and linear movement-integration in generating spatial maps. A third epoch began when investigators turned their attention to the entorhinal cortex, which led to the discovery of grid cells and border cells. This review will show how ideas about integration of self-motion cues have shaped our understanding of spatial representation in hippocampal-entorhinal systems from the 1970s until today. It is now possible to investigate how specialized cell types of these systems work together, and spatial mapping may become one of the first cognitive functions to be understood in mechanistic detail.

海马结构中的空间表征：历史。

自从记录了首位细胞并随后制定了认知图论以来，对海马结构中空间表示的研究已逐步展开。早期研究试图验证位置细胞活动的空间性质并确定其感觉起源。一个新的时代开始于头部方向单元的发现，以及意识到角度和线性运动整合在生成空间地图中的重要性。第三个时代开始于研究人员将注意力转向内嗅皮层，从而发现了网格细胞和边界细胞。这篇评论将展示关于自运动提示整合的思想如何塑造了我们对从1970年代到今天的海马-肠胃系统的空间表征的理解。
