  Background & Aims: Schizophrenia is characterized by a broad range of unusual behaviors that cause profound disruption in the lives of the patients suffering from the condition. individuals with schizophrenia show dysfunction within brain lobes. The aim of this research was to compare brain posterior areas' wave activities in the schizophrenic patient with a healthy group.

  Materials & Methods: In this research 38 schizophrenic patients and 38 healthy individuals were studied. The results of Scale for Assessment of Negative Symptoms (SANS) and Scale for Assessment of Positive Symptoms (SAPS) showed that 18 patients had negative and 20 had positive symptoms. Q-EEGs of patients and control groups were obtained from six areas of parietal and occipital lobes and the results were compared with Hoteling Trace criterion.

  Results: The findings indicated that except 6 variables, in 18 related variables to parietal and occipital lobes there were significant differences. The means of two groups signified that in schizophrenic patients delta waves of these two lobes increased and theta and alpha waves decreased. Also in patients, beta waves of these two lobes in the left hemisphere decreased and in the right hemisphere increased.

  Conclusion: The decrease of beta waves in left hemisphere and its increase in right hemisphere in these lobes in schizophrenic patients were consistent with previous studies that say the activities of the right hemisphere in schizophrenic patients were higher than the left hemisphere.

  Keywords: Schizophrenia, Q-EEG, Brain waves, Parietal lobe, Occipital lobe
