Fig. 7.
Cerebellar connections involved in smooth pursuit. Mossy fiber projections from the frontal eye fields are shown in red and from the postrolandic visual areas in green. Cerebello-cortical-olivary climbing fiber loops of the C2 zone and the posterior interposed nucleus are shown in blue, the D1 zone and the caudal dentate nucleus loop in orange; its hatched segments have not yet been verified in primates. Abbreviations: Ai anterior interposed nucleus, C 2, C 2 Purkinje cell zone, D 1, D 1 Purkinje cell zone, F fastigial nucleus, FEF frontal eye field, MST medial superior temporal area, MT middle temporal area, NRTP nucleus reticularis tegmenti pontis, PEF parietal eye field (lateral intraparietal area), PI posterior interposed nucleus, SEF supplementary eye field, V1, V2 visual areas 1 and 2
