The alternation of optokinetic responses driven by moving stimuli in humans.

When the two eyes were exposed dichoptically to two oppositely moving patterns, the alternating OKN was elicited, in which the eye movements tracked the two moving stimuli alternately. In the present experiment, two oppositely moving stimuli were periodically exchanged between the eyes, the results showed that the alternation of OKN direction was not affected by this exchange. It suggests that alternating OKN was not controlled by rivalry between the two eyes but between two perceived motion patterns. Copyright 1998 Elsevier Science B.V.
