Fig. 1: Clustering of 59 axonal morphologies from ref. 25 with somata in the presubiculum.
From: Generating brain-wide connectome using synthetic axonal morphologies
A total number of five clusters is imposed here because28 reported five clusters in their clustering. A Clustering based on axon lengths in target regions where the axons terminate. B Projections of 59 virtual axons sampled with the GMMs defined by axon lengths (A). C Clustering based on the number of terminals in the regions where the axons terminate. D Using the number of terminals or axon lengths in target regions as feature vector for clustering was found to be equivalent. A linear relationship was found between number of terminals and path lengths of axons in the regions. GMM Gaussian mixture model, CTXpl Cortical plate, PAL Pallidum, HY Hypothalamus, TH Thalamus.
