    Abstract:
    Gender-related differences in EEE coherence were studied in young male and female university students during performance of Stroop task, in which color and word could be congruent or incongruent and spatially integrated or separated. The most clear-cut gender-related differences in the EEG coherence were revealed in the alpha2 and beta frequency bands. In the alpha2 band, gender-related differences in the interhemispheric coherence were associated with spatial characteristics of stimuli: left or right presentation and features of mutual localization of relevant and irrelevant stimuli. These differences were observed when information was addressed to the left hemisphere. Gender-related differences associated with spatial organization of stimuli were also observed for intrahemispheric beta1 coherence. Under conditions of the spatial separation of relevant and irrelevant stimuli, only females demonstrated enhancement of coherence in response to the right-side stimulus presentation as compared to the left-side presentation. It was shown that, during the differentiation of the semantic meaning of verbal stimuli, gender-related differences were caused by the features of integration of beta2 oscillators in the posterior cortical regions. The results are indicative of qualitative gender-related differences in organization of both frontoparietal and lateral attention systems in actualization of selective processes.
