An ANOVA on apical intersections across Sholl rings indicated a significant main effect of treatment in the 150 μm Sholl ring (F (2, 27) = 3.9, p<0.05) (see Figure 4A). Further analysis using Tukey’s HSD post hoc tests indicated that the main effect was due to decreased intersections in the ET group compared to the IC group (Tukey’s HSD, p’s<0.05). An ANOVA on basilar intersections did not indicate any significant effects. Analysis of soma size in Layer II/III pyramidal neurons indicated a significant increase in the ET group compared to the NC group (F (2, 28) = 3.5, p < 0.05, Tukey’s HSD, p <0.05) (see Figure 4B).
