It is not known whether the optokinetic afternystagmus (OKAN) can be evoked by cyclo-rotatory optokinetic stimulation (C-OKst) or not. Accordingly, this study was designed to investigate the problem by using a rotating white dome with random dots. Optokinetic nystagmus (OKN) and OKAN in standing upright, supine, and prone positions were recorded and analyzed with an infrared-ray CCD camera and computed picture analyzer. During stimulation, rotatory OKN showed clearly, but there was no slow-rise component. The OKAN was continuously recorded and analyzed. The component of this OKAN was found only in the head-horizontal direction (yaw axis) in all different head positions. It appeared fairly constantly in the prone posture. The velocity storage mechanism (VSM) had to be charged by the C-OKst, but the OKAN (1st phase) appeared only in the yaw axis, not in the roll axis.
