Overlay of brain regions associated with PTSD by task design. Warm colors indicate regions of hyperactivity in PTSD patients during symptom provocation study designs (red) and cognitive-emotional study designs (yellow). Cool colors indicate regions of hypoactivity in PTSD during symptom provocation designs (purple) and cognitive-emotional designs (blue). Cog-Emo = Cognitive-emotional, DmPFC = dorsomedial prefrontal cortex, IFG = inferior frontal gyrus, L = left, midACC = mid anterior cingulate cortex, SMA = supplementary motor area, Sym Prov = symptom provocation, Thal = thalamus, vmPFC = ventromedial prefrontal cortex.
