Four knowledgeable referees support acceptance for the contributions, notably the development of a new model for system identification of bipolar cell responses to synthetic and natural stimuli which explains a variety of effects that align with our current understanding of BC circuits. I also recommend acceptance. However, please consider revising – to include the ablation study suggested by two of the reviewers. Please note that there was some confusion among the reviewers regarding your rebuttal. Why did you plot different cells for (A) and (B)? You also mentioned that the “generalization performance of the ablated models was surprisingly good”. Did this refer to chirps?
