Abstract
The authors performed spectral analysis of electroencephalograms (EEG), recorded awake, with eyes closed, in 13 patients with schizophrenia and 9 age-matched individuals without psychiatric diagnosis. We tested several possible parameterizations of the data, and two data-reduction strategies; these yielded similar results. Comparison of the two groups revealed a relative increase in alpha frequency activity in the frontal regions in the patient group. The authors believe that this finding is consistent with data from neuropsychologic tests, metabolic imaging studies, and evoked potential studies that suggest impaired activation of frontal brain areas in patients with schizophrenia.
