Overview of VBM results (ROI analyses).

Region	Side	Cluster size	BA	MNI coordinates			T-value
				X	Y	Z
Low > high
Hippocampus	Right	20	37	27	−38	−18	−3.42
High > low*

Differences of brain region comparing low and high HO-1 groups. *Means no areas were statistically significant different. BA, Brodmann’s Area; MNI, Montreal neurological institute; VBM, voxel-based morphometry; T-value is statistical t by two-sample t-test.
