The main goal of our study was to determine the EEG-patterns, which provide high originality of divergent task solving, defined on the base of alpha-rhythm individual frequency. The dynamics of power and coherence indexes in alpha-1, alpha-2 and alpha-3 subbands during the divergent and convergent tasks solving were analyzed. It was shown that the individuals from high thinking originality group have higher readiness to information perception, which is revealed in a higher depression of alpha-2 and alpha-3 rhythms during transition to rest state with eyes open. During the divergent task processing, an increase in frontal and fronto-central connections in alpha-2 subband was typical for groups opposite in sex and the originality level: for «original» males and «stereotype» females. In alpha-3-band, we observed the formation of level and character changes of intracortical interaction pattern, which was specific for each group and related to the sex of tested individuals and the level of originality of answers.

Keywords: creativity, alpha-subbands, EEG power, EEGcoherence, intercortical interations.
