Neural mechanisms for navigation in large space were investigated. We have already found the medial parietal neurons which related to process the scene and motor information for navigation. These navigation neurons may also process the place information and represent whole space by population. Furthermore, activity of those were affected by the context information of navigation route. We also found the navigation related neurons in the parahippocampal gyrus, which may process the scene information rather than motor information.
