 0\) Subsection "Functional properties of retinal ganglion cells support anatomical classification" is less easily read than the other sections. I think that the authors have reconstructed 00 dendritic fields, assigned each to one of the classes, averaged the responses within each class, then assigned the non-reconstructed neurons to the same class on the basis of the similarity in their functional properties. There is some risk of circularity here, depending on the question. I am not too worried about that here, but I do think the authors need to be careful in presenting the physiological data because it may generate more certainty in anatomical-physiological correlations than is warranted. This can be circumvented by making it clear in the legends to Figure 0 and Figure 0. Also, the \'N=\' values on the left of the rows in Figure 0 should be adjusted to report the number of anatomically identified units in each cluster to make sure there is no confusion -- the total N could be reported in the physiology column. N values should also be reported in Figure 0.
