网格细胞和位置细胞在大鼠空间认知中起重要作用。位置细胞根据外部环境信息提供全局定位,而网格细胞则根据内部前庭信息提供路径整合的“神经里程计”。在本文中,我们描述了一个空间认知模型整合网格细胞和位置细胞的行为和神经生理学的大脑研究。网格单元放电是从线性振荡干扰模型产生的,该模型包括一个重置机制,以克服“神经里程计”读数中的错误。该模型在仿真中进行了评估。未来的工作进行了讨论,包括扩展的模型和评估下的物理机器人。
Grid cells and place cells have shown to play an important role in spatial cognition in rats. While place cells provide global localization from external environment information, grid cells provide a “neural odometry” for path integration from internal vestibular information. In this paper we describe a spatial cognition model integrating grid cells and place cells from behavioral and neurophysiological brain studies in rats. Grid cell firing is generated from a linear oscillatory interference model that includes a reset mechanism to overcome errors in “neural odometry” readings. The model is evaluated in simulation. Future work is discussed including extensions to the model and evaluation under physical robots.
