Figure 1. Regional gray matter volume reduction in recent onset PTSD compared with normal controls.

The significant reduction regions in trauma survivors with recent onset PTSD (n = 10) compared with normal controls (n = 20) are rendered onto the standard T1 template of Montreal Neurological Institute. The trauma survivors with recent onset PTSD had a significantly decreased gray matter volume in the left ACC (p<0.05, FWE corrected, with k>50 voxels). ACC: anterior cingulate cortex.
