The components of the lateral column of the cord traceable intothe medulla—the direct cerebellar and Gowers tract and the long paths of the lateralground-bundle—for the most part, with the exception of the direct cerebellar tract,pass beneath or to the outer side of the olive. The superficially placed direct cere-bellar tract gradually leaves the lateral area and passes outward and backward to jointhe inferior cerebellar peduncle by which it reaches the cerebellum.
