My work focuses on understanding the role of the cerebellar nodulus and uvula (NU) in motion perception and spatial navigation. We aim to understand how NU processes the vestibular signals arriving directly or indirectly from the vestibular organs (otolith and semicircular canal afferents). Specifically, we study the role of NU inhibitory interneurons in vestibular signal transformation. Our recent work has shown that NU Purkinje cells (the sole output of the cerebellar cortex) exclusively encode inertial motion (translation) by combining otolith signals with a transformed signal from the semicircular canals. It is still unknown however, whether translation is computed within the NU or it is sent there already computed by its inputs, e.g. the vestibular nuclei. To answer these questions I will evaluate the role of GABAergic interneurons within the NU in the transformation of head- centered vestibular afferent information into inertial motion. Together, these experiments will elucidate the role of inhibitory interneurons in the signal transformations carried out by the NU and have the potential of unveiling general rules of cerebellar function. Furthermore, a better understanding NU function could lead to the development of therapies for rehabilitation following disease and trauma of the vestibular organs or the cerebellar cortex. My goal is to use this understanding to aid in the development of prosthetics and other tools for treating diseases, as well as to provide guidance to molecular approaches aimed to repair lost brain function.
