Figure 3. K-means analysis of the diverse porcine retinal ganglion cell population. A: The Silhouette plot was elaborated according the best clustering distribution, taking into account the given parameters of soma major axis length, soma area size, and dendritic field area size for all retinal ganglion cells. The number of individuals in each cluster is defined and the mean value of the silhouette plot (0.49) is also indicate (where n is the sampling size and represent the total Number of analyzed cells; a, b, and c represent the three obtained clusters; the cluster a contains 96 cells; the cluster b 60 and the cluster c 14). B: The representation of the principal analysis components was carried out. The representative clustering plot for all retinal ganglion cells showed their distribution into three major clusters (+: cells into cluster a; Δ: cells into cluster b; ¢′: cells into cluster c).
