Gowers column an·te·ri·or spi·no·cer·e·bel·lar tract [TA] a bundle of fibers originating in the base of the posterior horn and zona intermedia throughout lumbosacral segments of the spinal cord, crossing to the opposite side and ascending in a peripheral position in the ventral half of the lateral funiculus. In its ascent through the rhombencephalon, the tract curves sharply dorsalward along the rostral border of the trigeminal motor nucleus, entering the cerebellum in a caudal direction over the surface of the superior cerebellar peduncle, and terminating as mossy fibers in the granular layer of the cortex of the cerebellar vermis. The bundle conveys proprioceptive and exteroceptive information largely from the opposite lower extremity, although some of its fibers recross in the cerebellum. Synonym(s): tractus spinocerebellaris anterior [TA], ventral spinocerebellar tract ☆ , Gowers column, Gowers tractGowers columnThe tract of ascending fibers anterior to the direct cerebellar column and on the lateral surface of the spinal cord.
