| Research Abstract |
It is possible that depressive patients have dysregulation of cognitive processes due to hyperactivity of anterior cingulate cortex. We measured feedback negativity, one of event-related brain potential and functional MRI during imposing decision-making and reward prediction problems, respectively. The amplitude of feedback negativity was decreased in schizophrenia patients compared to controls. Reward prediction induced increased neuronal activities in the dorsal anterior cingulate cortex and ventral striatum of healthy subjects using a functional MRI. Further studies are ongoing to evaluate these neurophysiological measures in depressed patients.
