The electroencephalogram (EEG) during information processing is influenced by specific changes in brain electrical activity. Based on the theory of a disturbed information processing in schizophrenics we analysed auditory stimulus induced EEG changes by Fast Fourier Transformation. The most important of the significant stimulation dependent EEG power changes were measured in the 0.5-3.5 Hz and 10-13.5 Hz frequency bands in the left parietal lead. In a multivariate analysis the separation of the subjects examined into acute schizophrenics and normals was incorrect in only 21% of the cases (resubstitution rate): using the pi-method an error of 31% was estimated.
信息处理过程中的脑电图（EEG）受大脑电活动的特定变化影响。基于精神分裂症患者信息处理紊乱的理论，我们通过快速傅里叶变换分析了听觉刺激诱发的脑电图变化。在左顶叶导联中，最重要的、与刺激相关的脑电图功率显著变化出现在0.5 - 3.5赫兹和10 - 13.5赫兹频段。在多变量分析中，将受检对象分为急性精神分裂症患者和正常人时，只有21%的病例分类错误（重新代入率）：使用π方法估计错误率为31%。
