Results of between-group analysis for PTSD patients and healthy control participants, shown for hypothesized areas, in which there was a significant BOLD response for the contrast of No-Go minus Go stimuli, with controlling for inhibitory error^*

ACC = anterior cingulate cortex; BOLD = blood oxygen level dependent; L = left; MNI = Montréal Neurological Institute; mPFC = medial prefrontal cortex; PTSD= posttraumatic stress disorder; R = right; VLPFC = ventrolateral prefrontal cortex.
↵* Using total commission error as a covariate, significant differences in behaviour were found only between the healthy control group and the PTSD group.
↵† Significance set at p < 0.005.
