Vestibular signals in the posterior vermis of the alert monkey cerebellum.
Head velocity-related modulations in Purkinje cell activity were observed in lobules VI and VII of the cerebellar vermis. The sensitivities and phase shifts with respect to head velocity of Purkinje cells were comparable with vestibular responses observed in the fastigial nuclei. The results support the hypothesis of a vermal target velocity correlate and necessitate the inclusion of vermal lobules VI and VII among the cerebellar regions involved with vestibular information processing.
