20 psychiatric patients without pharmacologic therapy and an homogeneous control group of 19 healthy subjects have been submitted to an electroencephalographic (EEG) investigation. Computerized spectral analyses of the main EEG frequency bands have been performed. The spectra have been determined by some geometrical descriptors: the relative activity, the barycentric frequency and the barycentric radius; also classic descriptors have been used as complementary ones. In the EEG profile significant differences between patients and healthy subjects have been found. Some differences have also been observed among subgroups of schizophrenic patients. The geometrical descriptors applied in the EEG analysis are suggested as a useful method in the description of the basic characteristics of the main EEG frequency bands.
20名未接受药物治疗的精神科患者和19名健康受试者组成的同质对照组接受了脑电图（EEG）检查。对主要EEG频段进行了计算机频谱分析。频谱由一些几何描述符确定：相对活动、重心频率和重心半径；经典描述符也作为补充描述符使用。在EEG图谱中，发现患者与健康受试者之间存在显著差异。在精神分裂症患者亚组之间也观察到了一些差异。EEG分析中应用的几何描述符被认为是描述主要EEG频段基本特征的一种有用方法。
