Anticipated Threat Fmri Stress Task Reveals Dysfunctional Ventral Anterior Cingulate Activation Associated with Psychosis and Depression Symptom Burden

We used a stress-based functional neuroimaging task, reverse-translated from preclinical studies of stress, to test the hypothesis that abnormal limbic processing of stressful threat anticipation is associated with psychosis and affective symptoms in patients with SSD.
