Abstract

he rodent hippocampus has been thought to represent the spatial environment as a cognitive map. In this cognitive map, different spatial regions are assigned to different cell populations in the framework of rate coding, which is also is widely used in the associative memory. Then the article explains the formation and function of the two kinds of cognitive maps through the neural computational model and cognitive map building. The first one is the spatial vector map, it can perform self localization. At the same time,it can update the new detail information of the map. The other one is the goal-oriented vector map, it plays an important role in route finding. As an intermediate between the two types, the combination forms an effective and efficient way of path finding. This paper focused on applying this kind of cognitive map based path-finding methods to mental exploration model. Rely on the driving force of adaptation, we use the basic knowledge of the relationship between the locations stored in the first cognitive map, and form and reset the second cognitive map, finally solve a series of problems of finding new paths with the help of mental exploration, which is able to find a suitable path for the needs of different targets within a short time. The fresh idea of this paper can find its way to seek a simpler and safer answer of path-finding, and also provide a better basis for later to apply it to the programming of the robot system.
