Middle cerebellar peduncl

The medialmost compartment 4 of the rabbit flocculus is narrow and located at the border of the middle cerebellar peduncle (Fig. 147a,d). Compartments 1 and 3 are relatively rich in AChE and fuse in the dorsal and caudal white matter of the flocculus. The compartment 2 is poor in AChE and contains large Purkinje cell fibers in the myelin-stained sections. The fifth, most lateral compartment is the caudal extension of the C2 compartment of the paraflocculus. The compartments 2-5 continue, across the posterolateral fissure into the paraflocculus. In the first folium of the ventral paraflocculus of the rabbit (folium p of Yamamoto and Shimoyama, 1977), the compartments 1 and 3 enclose the dorsal tip of compartment 2 (Fig. 147b,c). Four compartments... 

Fig. 198. Diagram of the restiform body and middle cerebellar peduncle and their contributions to the cerebellar commissure. The dorsal spinocerebellar tract (DST) is part of the restiform body the ventral spinocerebellar tract (VST) enters the cerebellum after passing rostral to the trigeminal nerve. Voogd (1967).

The basal pontine nuclei, the nucleus reticularis tegmenti pontis and the adjacent paramedian pontine reticular formation are connected with the cerebellum through the middle cerebellar peduncle. Both the nucleus reticularis tegmenti pontis and the paramedian pontine reticular formation send their fibers through the midline raphe into the pes pontis (fibrae rectae), where they deflect laterally to occupy the deep stratum of the middle cerebellar peduncle.
