Climbing fiber - Wikipedia
Climbing fibers are the name given to a series of neuronal projections from the inferior olivary nucleus located in the medulla oblongata. [1] [2] These axons pass through the pons and enter the cerebellum via the inferior cerebellar peduncle where they form synapses with the deep cerebellar nuclei and Purkinje cells. Each climbing fiber will ...

In most models of cerebellum function, the climbing fibers regulate movement by modulating the effectiveness of the mossy—parallel fiber connection with the Purkinje cells. The Purkinje cells project in turn to the deep cerebellar nuclei. They are the only output cells of the cerebellar cortex.
Climbing Fiber - an overview | ScienceDirect Topics
Climbing fibers are the terminals of the axons arriving from inferior olive neurons that form strong synaptic connections to Purkinje cells. From: Fundamental Neuroscience (Fourth Edition), 2013
Climbing Fiber - an overview | ScienceDirect Topics
Climbing fibers are a unique structure of the cerebellum with no homologs elsewhere in the central nervous system. They originate from the inferior olive in the medulla oblongata. Each Purkinje cell is innervated by one climbing fiber, which forms numerous synaptic contacts (e.g., 26 000 in rat) with dendrites of a single Purkinje cell.

2023年7月27日 · Climbing fibers. These fibers arise from the inferior olivary nucleus and send collaterals to the deep nuclei before entering the cerebellar cortex. These fibers will reach Purkinje cells and will synapse over the proximal dendrites and cell bodies. The precise functions of these fibers are debated, with two theories.
