Values represent means ± SEMs of the data obtained for stereological and morphometrical analyses of three experimental groups: control, PSD96 h and SR21. Statistical analyses based on ANOVA and Tukey tests. Significance 𝑃 < 0 . 0 5 . *Different from control group and different from PSD96 h. RV: relative volume. AV: absolute volume.
