Regions related to task performance showing heightened activity in the trauma controls relative to both the patients with post-traumatic stress disorder and the healthy controls. Mean (standard deviation) blood oxygen level-dependent (BOLD) responses within : (a) left dorsolateral frontal cortex, Brodmann area 46 (x, y, z=−57, 33, 18) ; (b) left superior frontal cortex, Brodmann area 9/6 (x, y, z=−54, 6, 45).
