p286fig07.05 This figure shows the propagation through time of illusory contour offset from the rebounded cells that got direct inputs to the center of the contour.<BR>||  Persistence data and simulations.  Illusory contours persist longer than real contours (Meyer, Ming 1988; Reynolds 1981). When bottom-up inducers are inhibited by OFF cell rebounds, their offset gradually propagates to the center of the illusory contour.
