In healthy subjects, in a state of relative rest, with different individual profiles of asymmetry (20 right-handed and 10 left-handed subjects), a greater conjunction of electrical brain processes (estimated by mean EEG coherence levels) has been found in the dominant hemisphere as compared to the subdominant one, more distinctly expressed in the right-handed subjects. The maximum degree of interhemispheric asymmetry of the EEG coherence is observed in the posterior associative cortical areas. Specific interhemispheric theta-range differences are revealed as compared with other EEG frequency bands. Greater values are obtained of the correlation of the EEG symmetrical hemispheres points in the whole frequency band and in alpha- and beta-ranges in the right-handed subjects than in the left-handed ones.
在健康受试者处于相对休息状态时，针对不同个体的不对称情况（20名右利手和10名左利手受试者），与非优势半球相比，在优势半球发现了更显著的脑电活动联合（通过平均脑电图相干水平估计），在右利手受试者中表现得更为明显。脑电图相干性的半球间不对称程度在后部联合皮质区域最为显著。与其他脑电图频段相比，揭示了特定的半球间θ频段差异。在整个频段以及α和β频段中，右利手受试者脑电图对称半球点的相关性值高于左利手受试者。
