[Assessment of the role of the sensory innervation of the intraocular muscles in habituation of vestibulo-oculomotor reactions].

In rabbits, participation of the extraocular muscles' sensitive innervation in extinguishing of the eyes nystagmus elicited by periodical rotations, was studied. Either limitation or complete abolishing of the above muscles motor activity were used, as well as the passive forced movements of the eyes. No considerable difference was revealed between the intact and the experimental animals. In both cases the course of nystagmus extinguishing was the same. On the other hand, repeated forced movements of the eye had no effect on the reflectory evoked nystagmus. The data obtained suggest that the proprioceptive afferents of the extraocular muscles take no part in the habituation of vestibular-oculomotor responses.
