EEGs of 15 healthy subjects and 30 patients in early period after surgical ablation of tumours with basal localization, were investigated by means of monitor "Neuro-1" which allows to obtain in continuous regime characteristics of EEG dynamics according to power spectra and reveal the characteristics of intercentral relations of electrical brain processes by coherence and phase shifts. In healthy subjects in the period of transition from wakefulness to drowsiness highly coherent beta-rhythm (16-18 Hz) was revealed, preceeding typical picture of drowsiness and sleep. Study of the patients shows that certain characteristics of coherence and phasic shifts have an important prognostic value. Conclusion is made that for estimation of the functional state of healthy subjects during transition from wakefulness to drowsiness and of patients in early postoperative period the data on spectra of coherence are most informative.
利用“Neuro - 1”监测仪对15名健康受试者和30名基底部位肿瘤手术切除术后早期患者的脑电图进行了研究，该监测仪能够连续获取脑电图动力学的功率谱特征，并通过相干性和相位偏移揭示脑电过程的中央间关系特征。在健康受试者从清醒过渡到困倦的阶段，发现了高度相干的β节律（16 - 18赫兹），先于典型的困倦和睡眠状态。对患者的研究表明，相干性和相位偏移的某些特征具有重要的预后价值。得出结论，对于评估健康受试者从清醒过渡到困倦时的功能状态以及术后早期患者的功能状态，相干性谱数据最具信息量。
