Study Notes
- Both the cerebellum and basal ganglia influence motor cortex for movement control and refinement.
- The cerebellum has three layers and four pairs of deep nuclei for input and output.
- The cerebellum is composed of three major lobes: anterior, posterior, and flocculonodular.
- The cerebellar cortex is three-layered and uniform throughout.
- The five cell types in the cerebellum are granule cells, Purkinje cells, Golgi cells, basket cells, and outer stellate cells.
- There are two types of inputs from the cerebellum: mossy fiber and climbing fiber.
- Mossy fibers are excitatory to granule cells and parallel fibers are formed by the axons of granule cells.
- The cerebellum's older parts are the nodulus and flocculus, associated with vestibular nuclei.
- Fissures between major parts of the cerebellum are the primary fissure and the posterior lateral fissure.
- The cerebellum has one excitatory cell type (granule cells) and four inhibitory cell types that use GABA as a transmitter.
