|---|---|---|---|---|
| Volume of the granule cell layer (mm3) | 0.356 ± 0.009 | 0.373 ± 0.008 | 0.336 ± 0.010 | 0.365 ± 0.013 |
| Neuronal density | 9.91 ± 0.37 | 9.47 ± 0.23 | 9.55 ± 0.40 | 9.21 ± 0.16 |
| Absolute number of granule cells | 3.90 × 105 ± 0.13 × 105 | 3.91 × 105 ± 0.08 × 105 | 3.57 × 105 ± 0.18 × 105 | 3.74 × 105 ± 0.16 × 105 |
Ctr-6, Six-month-old control mice; Ctr-18, 18-month-old control mice; Enr-6, 6-month-old enriched living mice; and Enr-18, 18-month-old enriched living mice. Sample volume was 9000 μm3. The numbers are mean ± SEM. ANOVA revealed that no significant differences exist among the groups.
