Located at the back of the skull, the cerebellum is a key brain region for controlling motor functions, but it also contributes to higher cognitive functions, including social behaviors.

Use different models of the mouse (The term mouse is an obscure generic name that could be assigned to French speakers before…) And genetic tools, the researchers show that, in a specific type of cerebellar cell, changes in D2R levels alter social communication and preference for social novelty, without affecting motor functions.
