[Functional organisation of the cerebellum: a neuroanatomical approach]

Knowledge of the functional organisation of the cerebellum has progressed. The phylogenetic and anatomical divisions within the cerebellum, which have long been used to describe cerebellar functions, are now too simplistic. The understanding of cerebellar motor functions requires knowledge of a neuroanatomical division based on the afferents and the corticonuclear organisation of the cerebellum. Non-motor cerebellar functions are even more poorly systematised, but the rapid progress being made in neuroscience and neuroimaging techniques should enable them to be better understood.
