This project investigates the dorso-ventral organization of place cells in the hippocampus and grid cells in the enthorinal cortex generating new experimental rat studies involving obstacle cluttered environments and developing a new computational model based on theses studies producing a multi-scale representation of space exploited by rats and robots for spatial navigation. The results of this work demonstrated the relevance of both dorsal and ventral place cell during rat and robot navigation. The computational model included the integration of place cells in the Hippocampus and grid cells in the Enthorinal Cortex in providing a multi-scale space representation exploited by rats and robots during navigation in goal-oriented tasks that involve learning.
