Similarities and differences of rodent retinal ganglion cells with other neurons within and across clusters. (A) All rodent retinal ganglion cells together with blowfly tangential cells (cluster a) show highest branching density along PC1 compared to others metadata groups. The human basal pyramidal cell cluster (b) is highlighted for comparison. PC6 separates the tangential and ganglion cells, showing sub-cluster differences. The retinal cells also show a pattern of increasing partition asymmetry with increasing branching density. (B) Sample images of retinal ganglion cells (top), blowfly tangential cells (middle), and human basal pyramidal cells (bottom). NeuroMorpho.Org IDs of these neurons from left to right: 06464, 05352, 05405, 06652, 01895, 06640, 03723, 03724, 03722. (C) Rodent ganglion cells have larger amplitude angles compared to human basal pyramidal cells (and most other cell classes). (D) Rodent ganglion cells also display shorter branch length, corresponding to higher branching density. (E) The blowfly neurons, while sharing similar branch path length and amplitude angles with the retinal cells, have higher topological asymmetry.
