Activity of forelimb muscles under vestibular stimulation in guinea pigs with cerebellum removed.
Using decerebrate guinea pigs, we investigated the effect of complete removal of the cerebellum upon the influence of the vestibular system over the modulation of locomotor activity. It was found that the influence of the vestibular system over locomotor activity is preserved after removal of the cerebellum. The dynamic characteristics of the vestibular-spinal influences in cerebellectomized animals differ insignificantly from those of animals with an intact cerebellum. It is concluded that preservation of cerebellar-vestibular connections is not a necessary condition for the realization of vestibular influences upon locomotor activity.
