Figure 2. Ward’s dendrogram for retinal ganglion cells. The Ward’s method showed that retinal ganglion cells (RGCs) could be differentiated into three clusters (A, B, C). The obtained dendrogram for cluster analysis is represented here. The relative similarity of cells (x-axis) was shown in the linkage distance (y-axis) for all RGCs analyzed (n=170). The cluster origin for the cluster obtained in this work was designated with the corresponding letter. A continuous 3 pt-weight line divides the three main clusters in the study.
