The left panel shows the motion of the field and the stimulus relative to the retina. A retinal landmark is indicated by the white diamond. The right panel indicates how the field and stimulus are perceived to move as per the model in the supplementary discussion section. Settings: field: gain = 1, angle = 180; stimulus: gain = 1, angle = 180. In this simulation, both the field and the stimulus are slipping across the retina in a direction that is consistent with eye motion but at double the rate of eye motion. They are not moving relative to each other. This condition was tested in experimental condition C.
