The Cerebellar Nuclei (CN) are the sole output of the cerebellum, integrating and relaying information computed in the cerebellar cortex and transmitted by Purkinje cells, before sending it to the downstream targets of the cerebellum. The cerebellum receives two types of afferents: mossy fibers (sensory-motor context) and climbing fibers (teaching signals). These inputs project to the cerebellar cortex, with some also sending direct excitatory collaterals to the CN. However, little is known about the functional properties and the impact of these excitatory inputs on the firing of cerebellar nu
