A. Brain regions associated with PTSD across symptom provocation and cognitive-emotional tasks in the whole-brain voxel-wise analysis.B. Bilateral amygdala activity is observed after including symptom provocation and cognitive-emotional ROI studies to the whole-brain voxel-wise results. Areas of hyperactivation in PTSD (PTSD > Control) are shown in yellow and areas of hypoactivation in PTSD (Control > PTSD) are shown in blue. Amy = amygdala, IFG = inferior frontal gyrus, L = left, midACC = mid anterior cingulate cortex, R = right, vmPFC = ventromedial prefrontal cortex.
