posterior spinocerebellar tract


Definition: a compact bundle of heavily myelinated, thick fibers at the periphery of the posterior half of the lateral funiculus of the spinal cord, originating in the ipsilateral thoracic nucleus (column of Clarke) and entering the cerebellum by way of the inferior cerebellar peduncle. Terminals end as mossy fibers in the granular layer of the cortex of the cerebellar vermis and, via collaterals, in the cerebellar nuclei. The bundle conveys largely proprioceptive information originating from the annulospiral nerve endings surrounding muscle spindles and from Golgi tendon organs.

Synonym(s): tractus spinocerebellaris posteriorTA, dorsal spinocerebellar tract, Flechsig tract
