: any of four nerve tracts which pass from the spinal cord to the cerebellum and of which two are situated on each side external to the crossed corticospinal tracts:a: a posterior tract on each side that arises from cells in the nucleus dorsalis especially on the same side and passes to the inferior cerebellar peduncle and vermis of the ...
