Figure 5From: Sparse identification of contrast gain control in the fruit fly photoreceptor and amacrine cell layerOutput of the identified DNP model of the photoreceptor. (a) The stimulus presented to the photoreceptor; 5% of the stimulus was used for identification. (b) Comparison of the output of the detailed biophysical photoreceptor model (blue) with the output of the DNP model (red) and the output of the model without normalization, i.e., with \(\mathcal{T}_{1}\) only (yellow)Back to article page
