Fig. 5.

Bar graphs showing peak voxel values in brain regions where significant group differences were observed. In each panel, the group mean for veterans with PTSD before treatment (aqua), veterans with PTSD after treatment (red), and healthy controls (green) is shown for the peak voxel in a specific time window and brain area where group differences were observed. The legend appears on the right, and error bars reflect one standard error of the mean. These graphs illustrate the widespread normalization of theta and alpha oscillatory responses following attention training in veterans with PTSD
