Both groups of input fibers of cerebellum (mossy, climbing) start 2 pathways:
- project directly to the deep nuclei
- project to cerebellar cortex, which then (after some processing) sends projection back to deep nuclei through Purkinje cells.
What is the purpose of such an architecture?
And closely related question: is the input information to DCN (the first pathway) and to cerebellar cortex (the second pathway) the same?
