BACKGROUND Neuroimaging studies report that individuals with posttraumatic stress disorder show abnormal responses in the amygdala and medial prefrontal cortex (mPFC)/anterior cingulate cortex (ACC) during exposure to traumatic reminders. However, neural responses arising in the early aftermath of a traumatic event have not been studied. METHODS Twenty-two motor vehicle collision survivors and 12 nontraumatized control subjects participated. Regional cerebral blood flow (rCBF) was measured… CONTINUE READING
