[Relation between the asymmetry of optokinetic nystagmus and optovestibular and vestibulo-autonomic stability].

Comparative quantitative analysis of physiological asymmetry of the optokinetic nystagmus produced predominantly by central optokinetic stimulation (field of vision = 30 degrees) or peripheral stimulation (field of vision = 110 degrees) reveals an objective correlation between the asymmetry coefficient of the central optokinetic nystagmus with respect to the angular velocity of its slow phase and susceptibility to motion sickness caused by Coriolis and pseudocoriolis acceleration, the nystagmus velocity being up to 45 deg/sec.
