How do rodents' and primates' differences in visual perception impact the way the brain constructs egocentric and allocentric reference frames to represent stimuli in space? Strikingly, there are important similarities in the egocentric spatial reference frames through which cortical regions represent objects with respect to an animal's head or body in rodents and primates. These egocentric representations are suitable for navigation across species. However, while the rodent hippocampus represents allocentric place, I draw on several pieces of evidence suggesting that an egocentric reference frame is paramount in the primate hippocampus, and relates to the first-person perspective characteristic of a primate's field of view. I further discuss the link between an allocentric reference frame and a conceptual frame to suggest that an allocentric reference frame is a semantic construct in primates. Finally, I discuss how views probe memory recall and support prospective coding, and as they are based on a first-person perspective, are a powerful tool for probing episodic memory across species.
啮齿动物和灵长类动物在视觉感知上的差异如何影响大脑构建以自我为中心和以客体为中心的参照系来表示空间中的刺激？引人注目的是，在啮齿动物和灵长类动物中，大脑区域代表相对于动物头部或身体的物体的以自我为中心的空间参照系有重要的相似之处。这些以自我为中心的表示方式适合跨物种导航。然而，虽然啮齿动物的海马体代表着以客体为中心的位置，但我引用了一些证据表明，以自我为中心的参照系在灵长类动物的海马体中至关重要，并且与灵长类动物视野的第一人称视角特征有关。我进一步讨论了以客体为中心的参照系和概念框架之间的联系，以表明在灵长类动物中，以客体为中心的参照系是一种语义结构。最后，我讨论了观点如何探测记忆回忆并支持前瞻性编码，并且由于它们基于第一人称视角，因此是跨物种探测情景记忆的有力工具。
