脾后皮层与空间信号相关的脑区密切相关。为了测试它是否也编码空间，当大鼠在开阔的场地上行走时，记录单个细胞。如在早期的工作（L. L. Chen， L. H. Lin， C. A. Barnes, & B. L. McNaughton, 1994）。L. L. Chen， L. H. Lin， E. J. Green， C. A. Barnes, & B. L. McNaughton, 1994)，作者发现头部方向细胞具有与其他区域相似的特性。这些细胞有轻微的预见性。另一种类型的细胞对特定的位置、方向和运动组合发出信号，这表明每当大鼠使用特定的运动行为接近特定的位置时，它们就会发出信号。剩下的细胞不能被清楚地分类，但也显示出与一个或多个空间运动变量的显著相关性。脾后皮层包含空间和运动相关信号并与运动皮层相连的事实表明，它可能在路径整合或导航运动计划中发挥作用。
The retrosplenial cortex is strongly connected with brain regions involved in spatial signaling. To test whether it also codes space, single cells were recorded while rats navigated in an open field. As in earlier work (L. L. Chen, L. H. Lin, C. A. Barnes, & B. L. McNaughton, 1994. L. L. Chen, L. H. Lin, E. J. Green, C. A. Barnes, & B. L. McNaughton, 1994), the authors found head direction cells with properties similar to those in other areas. These cells were slightly anticipatory. Another cell type fired to particular combinations of location, direction, and movement, which suggested that they may fire whenever the rat approaches a particular location, using a particular locomotor behavior. The remaining cells could not be clearly categorized but also showed a significant correlation with one or more of the spatial-movement variables examined. The fact that the retrosplenial cortex contains spatial and movement-related signals and is connected with the motor cortex suggests that it may play a role in path integration or navigational motor planning.
