[Spatial organization of the beta2 EEG frequency band and effectiveness of the intellectual activity in humans].

[Article in Russian]

Abstract

Features of spatial organization of the beta2 EEG frequency band were studied in subjects with different speed and accuracy during task performance of the memorizing and subsequently reproducing of the sequence of signals on monitor screen. Students who had reached a high speed and accurately performed intellectual tasks were characterized by high lability of the coherent relations in the beta2 EEG range, which manifests itself in a significant coherence increase during memorization and reproduction of the signal sequence compared to the initial state. In contrast, in individuals who needed more much time for making decisions and mistakes, the number and structure of coherent relations from stage to stage of activity considerably did not change.
