Abstract

Optokinetic Nystagmus (OKN) induced by moving compound gratings was investigated. It was found that OKN sometimes tracks the coherent motion of the rigid plaid in a single direction, and sometimes tracks alternately the transparent motion of two component gratings in different directions, as Dual Altemate OKN. It was also found that the duration of OKN tracking coherence increases as the moving speed of the component gratings d creases, and as the angle between their moving directions decreases. The results also showed that the effect of angle plays a dominant role.
