人们普遍认为空间关系和空间信息在认知地图的形成中起着至关重要的作用。然而，目前尚不清楚世界的哪些属性被明确编码，以及这些属性如何有助于形成这样的地图。有人提出，空间关系要么是分类编码的，这样物体的相对位置就用介词来定义；或者作为视觉坐标，以便表示物体之间的精确距离。来自人类和动物研究的新证据表明，在主动空间导航过程中，不同的神经回路可能是物体位置分类和协调表征的基础。在这里，我们回顾了海马体结构对编码坐标信息至关重要的假设的证据，而顶叶皮层对编码分类空间信息至关重要。本文的综述为主动空间导航中这两个区域的功能和潜在的相互作用提供了新的视角。
It is generally accepted that spatial relationships and spatial information are critically involved in the formation of cognitive maps. It remains unclear, however, which properties of the world are explicitly encoded and how these properties might contribute to the formation of such maps. It has been proposed that spatial relations are encoded either categorically, such that the relative positions of objects are defined in prepositional terms; or as visual coordinates, such that the precise distances between objects are represented. Emerging evidence from human and animal studies suggests that distinct neural circuits might underlie categorical and coordinate representations of object locations during active spatial navigation. Here we review evidence for the hypothesis that the hippocampal formation is crucial for encoding coordinate information, whereas the parietal cortex is crucial for encoding categorical spatial information. Our short review provides a novel view regarding the functions and potential interactions of these two regions during active spatial navigation.
