Observations on Central Mechanisms Common to Vestibular and Optokinetic Nystagmus

Abstract

The covariation of optokinetic and vestibular nystagmus before and after administration of nicotine was studied. The results indicate that the amplitudes of the vestibular and the optokinetic nystagmus have a common central programming and that the speed of the slow components of the vestibular and the optokinetic nystagmus are influenced by a common central damping mechanism.
