Climbing fibers and mossy fibers
WebJun 16, 2014 · Unlike the mossy fibers and climbing fibers, the histaminergic afferent fibers, a third type of cerebellar afferents, extend fine varicose fibers throughout the cerebellar cortex and nuclei. Histamine receptors, belonging to the family of G protein-coupled receptors, are widely present in the cerebellum. WebClimbing fibers (which are the axons of the inferior olive cells) 4. Integrate input 5. Send inhibitory output to the deep cerebellar nuclear cells (cortical inhibitory loop) ii. Mossy fibers: a. Axons of pontine nuclei cells which carry the information about the plan of the movement that comes from the motor cortex b.

WebStellate cells are neurons in the central nervous system, named for their star-like shape formed by dendritic processes radiating from the cell body. Many stellate cells are GABAergic and are located in the molecular layer of the cerebellum. Stellate cells are derived from dividing progenitor cells in the white matter of postnatal cerebellum. …

These nuclei receive inhibitory inputs from Purkinje cells in the cerebellar cortex and excitatory (glutamatergic) inputs from mossy fiber and climbing fiber pathways. Most output fibers of the cerebellum originate from these nuclei. One exception is that fibers from the flocculonodular lobe synapse directly on vestibular nuclei without first passing …
