Paramedian pontine reticular

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. 

The paramedian pontine reticular formation of the cat projects bilaterally to lobule VII and the caudal part of lobule VI and to the ansiform lobule, i.e. to the visual areas of the cerebellum involved in control of saccades (Gerrits and Voogd, 1986 Yamada and Noda, 1987). Fibers of the reticular nucleus of the pons distribute bilaterally, with ipsilateral predominance, to all lobules of the cerebellum, with the exception of the lobules I and X and the dorsal paraflocculus (Kawamura and Hashikawa, 1981 Gerrits and Voogd, 1986). This projection includes the flocculus and the adjacent part of the ventral paraflocculus (Fig. 203) (Gerrits and Voogd, 1989) and collateral projections to the cerebellar nuclei (see Section 5.6.). 

The PPRF (paramedian pontine reticular formation) has neurons that burst at frequencies up to 1000 Hz during saccades and are silent during periods of fixation, and neurons that fire tonicafly during...
