The spatio-temporal DNP model can exhibit adaptation to local luminance. A DNP with four photoreceptors and an amacrine cell (see Example 1 for details) is adapted to a background intensity level at the beginning of each trial. One of the photoreceptors is then provided a two-second long flash of light, while the inputs to the other photoreceptors are kept at the background level. The relationship between the steady state response of the photoreceptor and the light intensity of the flash is shown for each of the background levels
