Figure 6. MRI data of MAM and control, enriched and non-enriched.

Figure 6

At P22 MAM rats had significantly smaller total brain volume (A, p<0.001) and hippocampal volume (B, p<0.001). At P150, animals had undergone 128 days of either enrichment or non-enrichment. The effect of MAM was present in both total brain volume (C, p=0.015) and hippocampal volume (D, p<0.001). Enrichment increased total brain volume (C, p=0.024) and hippocampal volume (D, p=0.026) in both control and MAM animals. Error bars represent standard error.
