Figure 7.
Dendritic branch points become more distant from the soma during postnatal development. (A, B) Bar graphs illustrate the mean ± SD of the total number of primary dendrites (A) and branch points (B) for BLA principal neurons at each time-point (n = 8). (C) The proximity of branch points to the soma was derived from Sholl analyses on reconstructed neurons with 40 µm thick rings, and the proportion of total branch points found in each ring is plotted as mean ± SEM (n = 8). The results of Tukey’s tests following two-way ANOVA are depicted in inset grids for Sholl rings with significant effects of age, namely those centered at 20, 100, and 140 µm from the soma (* P < 0.05; ** P < 0.01; *** P < 0.001; NS: not significant).
