A previous study of relationships between EEG and somatosensory evoked potential (SEP) measurements in psychiatric patients showed correlations between EEG and SEP amplitudes to be negative in nine neurotic patients and positive in nine age- and sex-matched nonpatients. The present study attempted to replicate this finding in 35 neurotics and 35 age- and sex-matched nonpatients. Data involved amplitudes of SEPs to right median nerve stimuli from frontal, central, and parietal leads and central and parietal EEG amplitudes (eyes open and closed), both obtained in the context of our comprehensive EP recording procedure. Correlations between SEP and EEG amplitudes in controls were generally positive, while those in patients tended to be negative or close to zero. No specific neurosis group differed from the others. The results confirm the previous finding in showing absence of normal EEG-SEP amplitude relationships in neurotic disorders.
先前一项关于精神病患者脑电图（EEG）与体感诱发电位（SEP）测量值之间关系的研究表明，9名神经症患者的EEG与SEP波幅之间呈负相关，而9名年龄和性别匹配的非患者则呈正相关。本研究试图在35名神经症患者和35名年龄和性别匹配的非患者中重复这一发现。数据包括来自额叶、中央和顶叶导联对右侧正中神经刺激的SEP波幅，以及中央和顶叶EEG波幅（睁眼和闭眼），这些都是在我们全面的诱发电位记录程序中获得的。对照组中SEP与EEG波幅之间的相关性通常为正，而患者组的相关性则倾向于为负或接近零。没有特定的神经症组与其他组不同。结果证实了先前的发现，即神经症性障碍中不存在正常的EEG-SEP波幅关系。
