Growing evidence suggests that the associative parietal cortex (APC) of the rat is involved in the processing of spatial information. This observation raises the issue of the respective functions of the APC and the hippocampus in spatial processing as well as of their possible interactions. In this paper, we review neuroanatomical, electrophysiological, and behavioral data that support the existence of such functional interactions. Our hypothesis is that the APC is involved in the initial combination of visuospatial information and self-motion information necessary for the integration of egocentrically acquired information into allocentrically coded information, the latter step being completed in the hippocampus. The dialogue between the hippocampus and the APC is therefore crucial, particularly when the elaboration and/or updating of an allocentric representation depends on complex combinations of visuospatial and self-motion information.
越来越多的证据表明，大鼠的联合顶叶皮质（APC）参与空间信息的处理。这一观察结果引发了关于APC和海马体在空间处理中的各自功能以及它们可能的相互作用的问题。在本文中，我们回顾了支持这种功能相互作用存在的神经解剖学、电生理学和行为学数据。我们的假设是，APC参与将以自我为中心获取的信息整合为以空间为中心编码的信息所需的视觉空间信息和自我运动信息的初始组合，后一步骤在海马体中完成。因此，海马体和APC之间的对话至关重要，特别是当以空间为中心的表征的构建和/或更新依赖于视觉空间和自我运动信息的复杂组合时。
