WebOct 4, 2024 · Their recent interesting finding that the LTD induction condition varies across different regions of the cerebellum is also explained. The optimal interval between stimulation of parallel fibers and that of a climbing fiber differs and seems to fit for a particular motor learning paradigm. WebClimbing fibers project to Purkinje cells and also send collaterals directly to the deep nuclei. [9] The mossy fiber and climbing fiber inputs each carry fiber-specific information; the cerebellum also receives dopaminergic, serotonergic, noradrenergic, and cholinergic inputs that presumably perform global modulation. [18] Climbing fibers are the name given to a series of neuronal projections from the inferior olivary nucleus located in the medulla oblongata. 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 … See more • Axon terminals • Parallel fiber See more • Climbing Fiber Discharge Regulates Cerebellar Functions by Controlling the intrinsic Characteristics of Purkinje Cell Output • Spatiotemporal Tuning of Optic Flow Inputs to the Vestibulocerebellum in Pigeons: Differences Between Mossy and Climbing Fiber Pathways See more industry hoses and fasteners
