A device is provided for studying the ability of at least one mouse to find its bearings in a maze, the device including a plurality of houses distributed around a central agora and in which at least one stimulator allows the at least one mouse to carry out certain activities and/or satisfy certain primary needs. Each house further includes at least one sensor for measuring the activity of the mouse in the house, and more particularly its use of the at least one stimulator. Finally, a sensor makes it possible to detect and measure the movements of each mouse in the device. Quantitative parameters originating from these measurements thus make it possible to highlight the quality of the geographical memory of the at least one mouse.
