The retrosplenial cortex (RSC) is an area interconnected with regions of the brain that display spatial correlates. Neurons in connected regions may encode an animal’s position in the environment and location or proximity to objects or boundaries. RSC has also been shown to be important for spatial memory, such as tracking distance from and between landmarks, contextual information, and orientation within an environment. For these reasons, it is important to determine how neurons in RSC represent cues such as objects or boundaries and their relationship to the environment. In the current work, we performed electrophysiological recordings in RSC while rats foraged in arenas that could contain an object or in which the environment was altered. We report RSC neurons display changes in mean firing rate responding to alterations of the environment. These alterations include the arena rotating, changing size or shape, or an object being introduced into the arena.

压后皮层 (RSC) 是与大脑中显示空间相关性的区域相互连接的区域。连接区域中的神经元可以编码动物在环境中的位置以及与物体或边界的位置或接近度。RSC 也被证明对空间记忆很重要，例如跟踪与地标之间的距离、上下文信息和环境中的方向。由于这些原因，重要的是要确定 RSC 中的神经元如何表示对象或边界等线索以及它们与环境的关系。在目前的工作中，我们在 RSC 中进行了电生理记录，同时大鼠在可能包含物体或环境被改变的场所觅食。我们报告 RSC 神经元显示响应环境变化的平均放电率变化。
