Description The inferior cerebellar peduncle (ICP) carries climbing fibers to the dorsal vermis, and these fibers have an inhibitory influence over the Purkinje cells. These Purkinje cells normally inhibit the ipsilateral fastigial nucleus, and the fastigial nucleus projects to the contralateral inhibitory burst neurons (IBN) within the paramedian pontine reticular formation (PPRF). The IBN project contralaterally to inhibit the VIth nucleus to prevent unwanted saccades in this direction, while facilitating saccades (via the excitatory burst neurons [EBN]) in the opposite direction.
