Figure 5.

Basal dendritic branching points in the hippocampal CA3 neurons of rats treated with 2, 4 and 6 ml kg⁻¹ body weight of CeA for 6 weeks and in age-matched control and saline treated rats at concentric zones (CZs) and total number of branching points. Each value represents the mean + SD of 8–10 neurons from each rat. F-value: 0.74, 44.64, 51.38, 28.66, 10.06 and 61.49 at the 0–20, 20–40, 40–60, 60–80 and 80–100 μm CZs and total number of branching points, respectively. Note the significant increase in dendritic branching points in 2, 4 and 6 ml kg⁻¹ CeA treated rats compared with control rats. Normal control versus 2 ml kg⁻¹ CeA: ^#P < 0.05, ^##P < 0.01; normal control versus 4 ml kg⁻¹ CeA: ^**P < 0.01, ^***P < 0.001; normal control versus 6 ml kg⁻¹ CeA: ^▴▴P < 0.01, ^▴▴▴P < 0.001 (one-way ANOVA, Bonferroni's test).
