"The dialog between the cerebellum and the sensori-motor cortices"
Résumé
The cerebellum contains more than half of the brain neurons and this proportion has been steadily maintained along with the expansion of the cerebral cortex, by the evolution of the mammalian brain. Indeed, the cerebellum and cerebral cortex are reciprocally connected. The cerebellum, long thought as a motor structure, is now recognized as a key player in a much wider spectrum of brain functions, and cerebellar dysfunction in the early life is a strongly suspected cause of autism-spectrum disorder. The nature of the dialog between the cerebellum and the cerebral cortex is currently poorly understood; for a long time, this dialog has been proposed to rely on closed loops between specific cortical and cerebellar areas. Using a combination of tracing, neurophysiology, chemo- and opto-genetics and behavioral studies, our recent work has expanded this view by showing that the cerebellum is indeed interacting with cortical networks and that multiple modes of interaction with the cerebral cortex underly the diversity of functional roles of the cerebellum.
