Summary: |
LGN responses to natural stimuli cannot accurately be predicted based on receptive field model. Two nonlinear effects are adaptation to contrast and luminance. These effects have been modeled by a separable model of local luminance and contrast gain control. Contrast was computed within the so-called supressive field that surrounds the classical receptive field. Predicted responses better predict LGN responses to natural stimuli. |
