Hippocampus spatial cognition neural basis and its application in agent

Spatial recognition is one of neural functions of rat's hippocampus. Head direction cells, grid cells and place cells play a major role in this function. Information about direction, distance, and location is integrated in the grid cells. Place cells receive information from grid cell firing and construct representation of the spatial environment of the brain. This representation is demonstrated to the foundation of the cognitive map. Spatial representations in the hippocampus emerge and develop as rat pups first begin to explore their environment outside of the nest and develop with age. This paper reviews and discusses the basis of neural functions including their biological properties, development process, modeling work and some applications based on this mechanism in agents.
