This study was conducted to determine whether the patterning of EEG and somatosensory evoked response (SER) variables, as determined by the correlations between them, differs with respect to psychiatric diagnosis. Subjects were 43 nonpatients and 90 psychiatric inpatients. SER modified recovery function recordings provided 36 variables, reflecting amplitude and its variations with different stimulus conditions. A 10-min left parietal EEG was quantitatively analyzed to give mean amplitude and frequency and variability measures. Correlations between EEG and ER variables were compared both for unmatched groups of nonpatients, schizophrenics, psychotic depressions, and nonpsychotics and for smaller age and sex-matched diagnostic groups. The results revealed a number of correlation differences between clinical groups. The nature of the differences suggested diagnostic specificity for EEG-ER patterning, which may provide a new, psychiatrically relevant electrophysiological variable.
本研究旨在确定脑电图（EEG）和体感诱发电位（SER）变量的模式（由它们之间的相关性确定）在精神科诊断方面是否存在差异。研究对象为43名非患者和90名精神科住院患者。SER修正恢复功能记录提供了36个变量，反映了不同刺激条件下的振幅及其变化。对10分钟的左侧顶叶脑电图进行定量分析，以得出平均振幅、频率和变异性测量值。比较了非患者、精神分裂症患者、精神病性抑郁症患者和非精神病患者的非匹配组以及年龄和性别匹配的较小诊断组的脑电图和诱发电位变量之间的相关性。结果揭示了临床组之间的一些相关性差异。这些差异的性质表明脑电图-诱发电位模式具有诊断特异性，这可能提供一个新的、与精神病学相关的电生理变量。
