The main object of the work was to elucidate the functional significance of different human EEG rhythms. Cross-correlation and spectral characteristics at the background and during mental work were studied in thirteen subjects by recording from four points of the left hemisphere. During intellectual load, spatial synchronization is enhanced between the biopotentials of most areas: interrelations between remote points are intensified which leads to the smoothing of the synchronization gradient existing in a state of rest. The alpha-rhythm becomes less pronounced everywhere in parallel to the decrease in synchronism of its fluctuations in different zones; at the same time low-frequency activity (delta-theta) increases both by the amplitude of oscillations and the capacity for its unidirectional shifts over the whole cortex. The least distinct change is observed in the beta-rhythm.
这项工作的主要目的是阐明不同人类脑电图节律的功能意义。通过记录左半球的四个点，对13名受试者在静息状态和脑力工作期间的互相关和频谱特征进行了研究。在智力负荷期间，大多数区域的生物电位之间的空间同步性增强：远处点之间的相互关系加强，这导致静息状态下存在的同步梯度变得平滑。随着不同区域α节律波动同步性的降低，α节律在各处都变得不那么明显；与此同时，低频活动（δ波-θ波）在整个皮层的振荡幅度和单向移动能力都增加了。β节律的变化最不明显。
