Post-Rotatory Nystagmus Following Decerebration in Guinea Pigs with Unilateral Gerebellar Lesions

Abstract

Conclusions

Post-rotatory nystagmus is still elicitable in guinea pigs with the cerebral hemispheres and thalamus removed. Neither the slow nor the quick components of the nystagmus were disturbed by decerebration at a level which passed through the superior colliculi dorsally and the mammillary body ventrally. The direction and intensity of the nystagmus remained within normal limits.

Lesions in the right half of the cerebellum did not modify the post-rotatory nystagmus, either alone or in conjunction with decerebration.
