Figure 7From: Sparse identification of contrast gain control in the fruit fly photoreceptor and amacrine cell layerEvaluation of the DNP model of the photoreceptor. (a) Gaussian noise stimulus with a bandwidth of 50 Hz. (b) Output of the photoreceptor model (blue) and of the identified DNP model (red, SNR 15.04 [dB]). The output of the identified model without normalization is shown in yellow (SNR 4.55 [dB])Back to article page
