脾后皮质与参与空间信号传递的大脑区域紧密相连。为了测试它是否也编码了空间，当大鼠在开阔的田野中航行时，记录了单个细胞。与以前的工作一样(LL Chen，LHLin，CA Barnes，&BLMcNaughton，1994；Ll Chen，LHLin，EJ Green，CA Barnes，&BLMcNaughton，1994)，作者发现了与其他区域相似的头部方向细胞。这些细胞有轻微的预期性。另一种类型的细胞向位置、方向和运动的特定组合发出信号，这表明每当老鼠接近特定位置时，它们可能会使用特定的运动行为进行发射。其余的细胞不能被清楚地分类，但也显示出与所检查的一个或多个空间运动变量的显着相关性。脾后皮质包含空间和运动相关信号，并与运动皮质相连，这一事实表明它可能在路径整合或导航运动规划中发挥作用。
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 (LL Chen, LH Lin, CA Barnes, & BL McNaughton, 1994; LL Chen, LH Lin, EJ Green, CA Barnes, & BL 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.(PsycINFO Database Record (c) 2016 APA, all rights reserved)
