Interactions of the nucleus of optic tract and vestibular system with gaze stabilization

We investigated the interaction of the vestibular nucleus (VN) with the nucleus of optic tract (NOT) for gaze stabilization. Observer movement changes the image that comes into the retina and the NOT vestibular interaction can be responsible for gaze stabilization. To verify this behavior the subjects were stimulated with visual patterns at 85 deg/sec. We waited 10 minutes for the eye´s accommodation because the room has a controlled light intensity separated by 11.5 lux. We observed that an angular displacement and a gain of a slow phase component of the nystagmus occurred when visual pathways are “on” and a decrease in amplitude of the signal showing that the NOT modulates the vestibular nucleus (VN)
