Abstract
In all species, unipolar brush cells (UBCs) are most abundant in the vestibulocerebellum. Yet, the role of these excitatory interneurons in the cerebellar input stage during visual and vestibular stimulation remains elusive. Here, we review the main morphological and electrophysiological properties of UBCs in the vestibulocerebellum, and we highlight their potential role in the flocculus during the coordination of compensatory eye movements. We advocate that they are well designed to contribute to expansion coding in the temporal domain, while preserving the identity of sensory and/or oculomotor encoding, so as to facilitate the optimal acquisition of all possible components of movement kinematics.
