p284fig07.02 Psychophysical data (top row) and simulation (bottom row) of how persistence decreases with flash illuminance and duration.<BR>||  Persistence data and simulations. (Francis, Grossberg, Mingolia 1994 Vision Research, 34, 1089-1104). Persistence decreases with flash illuminance and duration (Bowen, Pola, Matin 1974; Breitmeyer 1984; Coltheart 1980). Higher luminance or longer duration habituates the gated dipole ON channel more.  Causes larger and faster rebound in the OFF channel to shut persisting ON activity off.
