Lobus tuberis.—The tuber (tuber vermis) forms the most posterior division of theinferior worm and lies beneath the great horizontal fissure when that sulcus is continuousacross the mid-line. When th© folium cacuminis is small and buried, the tuber comesinto close relation with the lower end of the clivus, the three divisions of the worm justmentioned all springing from a common stalk of white matter. The tuber is of a general Fig. 941.

It presentsa few, from 2-4. superficial folia, which model the posterior pole of the worm, as viewed frombehind and above. The tuber is directly connected on each side with a considerable crescentic tract, thepostero-inferior lobule (lobulus semilunaris inferior), that is limited in front by the lateralextension of the postpyramidal fissure (sulcus inferior anterior) and behind by the great hori-zontal fissure. After emerging from the sulcus valleculte, the folia rapidly expand intoa lunate tract, from 15-25 mm. in its widest part, that forms the immediate posterior borderof the hemisphere.
