Asymmetry of Topographic Visual Evoked Potential P100 Determined by Global Field Power Measurement in Schizophrenia

Objects ： The authors attempted to assess asymmetric brain activity to topographic visual evoked potential P I00 determined by the Global Field Power Measurement in schizophrenia. Methods ： The subjects, 40 normal controls and 35 schizophrenics, were assessed in the absolute amplitude of topographic VEP P I00 by GFP. Results ： There were not significant differences in asymmetric brain activity between normal controls and schizophrenics. But, in O u the absolute amplitude of schizophrenics was significantly greater than that of normal controls. Conclusion : These results suggested that the schizophrenics may differ from normal controls not in asymmetricity(or laterality), but in brain activity.
