HT and dendritic spine morphology. A, Cumulative frequency plots of individual spine head diameters. Kolmogorov–Smirnov tests found no differences between groups (p > 0.7 for all pairwise comparisons). Similarly, mean spine head diameter was also unaffected by treatment (data not shown). B, Cumulative frequency plots of individual spine head volume. Kolmogorov–Smirnov tests found no differences between groups (p > 0.8 for all pairwise comparisons). Similarly, mean spine volume did not differ between groups (data not shown). See Results for details.
