Exploration of the left half of the cerebellum and brain stem from its inferior and medial aspect
Relations of folia of pyramis and tuber vermis to lateral parts of cerebellar hemisphere
The inferior half of the pyramis has been cut away and its remaining part reflected downward. The prepyramidal fissure is thus revealed. The folia of the upper aspect of the pyramis (15) can be traced laterally into the biventral lobule (3). The lobulus gracilis (2) extends medially deep within the prepyramidal fissure to become continuous with the deepest folia of the tuber on the superior wall of the fissure. Folia of the inferior semilunar lobule (1) all converge medially to become continuous with the remaining folia of the tuber (11).
