It repre-sents a coordinating center and might well be called the balancingbrain. The cerebellum consists of two lateral lobes, or hemispheres, anda middle lobe, or vermis. The two hemispheres are separated fromeach other ventrally by a groove, the vallecula, into which the oblon-gata, tegmental portion of the pons and the midbrain fit. Dorsallythe hemispheres are less widely separated. 382 THE NERVE SYSTEM The vermis and each hemisphere present a superior and an inferiorsurface. The superior surface of the vermis consists of the followinglobes, from before backward: {a) lingula cerebelli; (b) lobus centralis;. Fig. 272.—Superior surface of the cerebellum. {From a pnoiograph.) (c) culmen; (d) declive. The lobes of the superior surface of eachhemisphere represents a continuation of these with the exception ofthe lingula. The central lobe is continued into each hemisphere as
