Table 3. Decreased Gray-Matter Volume in Trauma-Exposed Firefighters Compared to Healthy Controls.

Brain Regions	Peak MNI Coordinates			Voxels (n)	Peak t Value
	x	y	z
Left superior parietal gyrus	−12	−69	54	1104	5.76
Left inferior temporal gyrus	−49.5	−45	−19.5	450	4.47

The regions that survived a whole-brain false discovery rate-corrected threshold of p < 0.05, cluster size > 20.
