Rabbits trained to discriminate vertical vs. oblique striations are unable to discriminate angular differences of 5°. In the present study the instabilities around the roll axis of the eyes were measured during visual discrimination. The results indicate that these instabilities are one of the causes of the rabbit's inability to discriminate angular differences of 5°.
