Relevant morphometrics for the BA type. Top left: per-type boxplots for the six morphometrics selected with RF BVI (RF BVI values shown, in blue, to the right). The most relevant morphometrics, mean arborization distance to soma (path_dist.avg), and mean remote bifurcation angle (remote_bifurcation_angle.avg), are shown in the upper part of the panel. Top right: a biplot of these six morphometrics, with the data projected onto the two principal components, found with principal component analysis (vectors represent morphometrics and the angles between them are indicative of their pairwise correlation). All morphometrics were correlated with either path_dist.avg or remote_bifurcation_angle.avg. Bottom left: the ten most relevant morphometrics according to KW, after removing those with absolute correlation >0.90 with a better ranked morphometric, with the KW p-values shown, in blue, to the right of the boxplot. These morphometrics included those relative to arborization distance from soma (e.g., euclidean_dist.avg, path_dist.avg), remote bifurcation angles (t.remote_bifurcation_angle.avg), the number of dendritic trees (d.N_stems), and axonal arborization along the radial direction (ratio_y). In addition to having sharper bifurcation angles and arborizing closer to the soma, especially in the radial direction, BA cells had more dendritic trees than non-BA cells
