我们研究了26名学生在相同难度的视觉空间任务中表现出不同的表现效率的脑电图α节律的频谱相干特征。在大脑两个半球的枕叶、顶叶、中央和颞叶区域之间观察到α EEG频带中的生物电位的更紧密的相干性。实验结果表明，在同一难度的视觉空间任务中，不同的执行效率与脑电α频段的生物电位同步水平有关。
We studied spectral-coherent characteristics of EEG alpha rhythm in 26 students demonstrating different performance efficiency in visual spatial tasks of the same difficulty. More close coherence of biopotentials in the alpha EEG frequency band was observed between the occipital, parietal, central, and temporal areas in both hemispheres of the brain. The results of the experiments showed that different performance efficiency in visual spatial task of the same difficulty was associated with different levels of biopotential synchronization in the EEG alpha frequency band.
