Supplemental Material
Files in this Data Supplement:
- Supplementary Fig. 1
-
Supplementary Figure 1 Histogram of the average difference in number of spikes for congruent minus anti-congruent responses, averaged over all four element pairs. Because responses were brief, corresponding spike rates would be much higher.
- Supplemental Movie 1
-
Supplementary Video 1 This movie shows that simply flashing the illusion on the retina, with fixation maintained, induces the illusory motion. To experience the effect, maintain fixation on the black dot while the movie loops.
- Supplemental Movie 2

Supplementary Video 2 This movie shows an example of the stimuli used in the psychophysical experiments. Element pairs from the illusion were repeated, each pair separated by a gray spacer. In sequential frames the gray spacers of a previous frame was replaced by the element pair, and the element pair of a previous frame was replaced by a gray spacer. Thus in a continuous cycle of frames there is no net motion, although there often is apparent motion, as in the illusion. To experience the effect, maintain fixation while the movie loops. Most people report an illusion of rightward motion.
