Taken from 20 neurons in each area. Tukey–Kramer method. *p < 0.05, **p < 0.01. (f) Basal dendrites length at every 10-µm position. Expressed as the summation of the length of single basal dendrites measured per 10 µm. Error bars denote SEM. Arrows indicate the positions where the basal dendrites length is significantly shorter in the PMd than in the other three motor-related areas (post hoc pairwise Tukey–Kramer method comparison of the basal dendrites length; p < 0.05). At most of the other positions, the basal dendrites length is significantly lower in the PMd than in at least one motor-related area. (g) Total number of intersections of basal dendrites in the motor-related areas. Taken from 20 neurons in each area. Tukey–Kramer method. *p < 0.05, **p < 0.01. (h) Intersection number at every 10-µm position. Expressed as the summation of the number of intersections on the concentric circles. Error bars denote SEM. Arrows indicate the positions where the intersection number is significantly smaller in the PMd than in the other three motor-related areas (post hoc pairwise Tukey–Kramer method comparison of the intersection number; p < 0.05). At most of the other positions, the intersection number is significantly lower in the PMd than in at least one motor-related area.
