Toet, A. Publication year 1991 Abstract The edges of straight bars in a square-wave luminance grating appear undulating to an observer when the retinal image of this pattern is in motion. The amplitude of the perceived undulations increases linearly with retinal image speed with an average slope of 30 ± 4 ms. The period of the motion-induced bulges is 2.5 ± 0.5° and shows no consistent variation with the retinal image velocity of the pattern. The close quantitative agreement between the spatiotemporal extent of this effect and recent estimates of the spatiotemporal parameters of human motion-sensitive mechanisms suggests that existence of motion-sensitive cells in the central nervous system that have a fixed time constant but change the shape and size of their retinal support with retinal image velocity.Rechte luminantieovergangen worden gegolfd waargenomen wanneer de retinale afbeelding beweegt. De gemeten amplitude en periode van deze golven zijn consistent met een model van spatiotemporeel zien waarin het bewegend beeld diskreet wordt bemonsterd.
