Optokinetic and vestibular interaction in normal man.
When we move our head with our eyes open the optokinetic and the vestibular systems are simultaneously activated. The optokinetic and the vestibular systems interact in a complex way. A full field optokinetic system can suppress or enhance vestibular reflexes according to the needs of the organism. It is likely that the summation of optokinetic and vestibular nystagmus is not linear, rather, the organism encodes retinal slip velocity as the important input.
