a

Presented as Mean ± Standard Deviation. ROI volume is in units of cm3. Volume relative to total intracranial volume (ICV) is defined as volume ratio and is unitless.

b

Spearman’s rank correlation analysis was applied to each test of correlation between age and ROI volume ratio. Cortex, CTX; Region of Interest, ROI.

*

P < 0.0056, which marks significance after applying Bonferroni correction for the nine regions tested.
