title: Spectral-coherent characteristics of EEG alpha rhythm in different efficiency of visual spatial task performance in humans.
abstract: 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.
