Linear addition of optokinetic and vestibular signals in the vestibular nucleus.

A simple model of the vestibuloocular reflex and the optokinetic system was used to simulate recent data on visual and vestibular responses of neurons in the vestibular nucleus. Contrary to a previous interpretation, the results support the hypothesis that the optokinetic and semicircular canal signals are combined simply by linear addition on the cells of the vestibular nucleus.
