Morphometry of the dendritic branches.
(A) Example dendrograms of the dendritic branches with average number of terminal segments (mouse in red, human in blue). (B) Boxplot diagrams for morphometric features of individual dendritic branches (red mouse, blue human, white line for median values, outliers shown with dots). Statistical significance p < 0.001 (***) and p > 0.05 (n/s). Total dendritic length and total terminal length are significantly longer in human SPNs (p = 0.00028 and p = 0.00008, respectively), while number of terminals and maximal order are similar (p = 0.74889 and p = 0.83002, respectively). (C) Mean length of the dendritic segment per topological order (order 1 for primary dendrites, etc.). Whisker lines for STD, unfilled boxes for single dendrites. (D) Relative length of the terminal segments normalised to the total length of the dendritic branch. The number of complete dendrites analyzed in (B-D) is 47 for mouse and 35 for human.
