summaryThe ability to maintain a sense of direction and location while moving in one’s environment is fundamental for our daily travels. Self-motion perception is a demanding problem in sensory integration, requiring the neural combination of visual signals (e. g., optic flow), vestibular signals regarding head motion, as well as somatosensory and proprioceptive cues. The cerebellum is adequately wired to combine the diversity of sensory signals to be monitored during self-motion and to fuel the navigation circuits. I will first illustrate how distinct cerebellar mechanisms are involved in the stability of place and direction coding depending on the availability of external sensory conditions. Then, I will specify how, from these multitude of sensory signals coming from the external world or generated by our own movement, the brain organizes the cortical and subcortical networks necessary to generate a behavior adapted to a complex situation. Finally I will describe the different anatomical pathways by which the cerebellum may influence the navigation networks and discuss how these results put forward a role for the cerebellum in memory and navigation.
