Movement through space is a fundamental behavior for all animals. Cognitive maps of environments are encoded in the hippocampal formation in an allocentric reference frame, but motor movements that comprise physical navigation are represented within an egocentric reference frame. Allocentric navigational plans must be converted to an egocentric reference frame prior to implementation as overt behavior. Here we describe an egocentric spatial representation of environmental boundaries in the dorsomedial striatum.
运动是所有动物的基本行为。环境的认知地图以一种与自我无关的参照系编码在海马体中，但构成物理导航的运动则是在自我参照系中表示的。在将行为表现出来之前，与自我无关的导航计划必须转换为自我参照系。在这里，我们描述了在背内侧纹状体中环境边界的自我中心空间表示。
