Abstract

In 20 guinea pigs, eye nystagmus of visual origin was investigated following stimulation of an optic nerve (optic nystagmus). The interactions between vestibular and visual inputs were observed by eliciting optic and labyrinthine nystagmus simultaneously. After complete removal of the vestibular nuclei, optic nystagmus was tested: It was no longer elicitable. On that basis, it is possible to conclude that the vestibular nuclei represent an essential station in the mechanism of optic nystagmus.
