 All of the reviewers read each other's reviews and agreed with the points raised in all of the reviews. Three important points are summarized below. The individual reviews (also below) detail these and other issues.  0\) The pathway specificity of the ganglion cell projections and the conclusions drawn from it needs to be described more carefully, with attention to the result that the specificity is not perfect. Also, important here is consideration of the relatively small number of cells in some cases. More detailed analysis of this data should include statistical tests of the significance of differences in projection patterns.  0\) The paper needs to be more transparent in describing the anatomical and physiological clustering approaches and their relationship with previous work. Specific examples of these issues are raised in the individual reviews. Again, statistical tests will be important here.  0\) The viral tracing and the Ntsr0-GN000-Cre line both have potential limitations/biases which should be considered in interpretation of those results.
