Event-related potentials and recognition of facial affects in schizophrenia

Introduction: Global functional but also specialised neuronal network disturbances such as abnormalities in processing faces are postulated to underlie the pathophysiology of schizophrenia. The aim of this study was to investigate electrophysiological differences between patients with schizophrenia and non-patient controls in processing emotional faces. Method: We examined 17 schizophrenic patients (8f/9m) and 21 normal controls (11f/10m). All patients were partially remitted and were on a constant neuroleptic medication for months. As stimuli, computer-generated male faces with different emotional affects (neut…
