The article treats problems related to the application of coherent analysis in studying the spatial synchronization of rhythms in the EEG. The significance of comparing the changes in the coherent functions (CF) of more combinations of cerebral structures, i.e. of intercoherent relations, is pointed out. Evidence is given that the observed equalization of the coherence according to different frequency ranges has a definite physiological significance, connected with the readjustment of the functional state of the nervous system on the basis of changes in the organization of the spatial rhythmic interrelations in it. Tests are made of several parameters for quantitative estimation of the changes in the intercoherent relations, which may be applicable to studying the organization of rhythms in the bioelectrical activity of the nervous system in different functional states in norm and pathology.
本文探讨了相干分析在研究脑电图节律空间同步中的应用相关问题。指出了比较更多脑结构组合（即相干间关系）的相干函数（CF）变化的重要性。有证据表明，根据不同频率范围观察到的相干性均等化具有明确的生理意义，这与基于神经系统中空间节律性相互关系组织变化的功能状态重新调整有关。对几个用于定量评估相干间关系变化的参数进行了测试，这些参数可能适用于研究正常和病理状态下不同功能状态时神经系统生物电活动中的节律组织。
