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.
我们研究的主要目标是确定脑电图模式，这些模式基于α波节律的个体频率，为发散性任务解决提供高度的原创性。分析了在发散性和收敛性任务解决过程中，α1、α2和α3子带中功率和相干指数的动态变化。结果表明，高思维原创性组的个体对信息感知的准备程度更高，这在睁眼过渡到休息状态时α2和α3节律的更高抑制中得以体现。在发散性任务处理过程中，α2子带中额叶和额中央连接的增加对于性别和原创性水平相反的组具有典型性：“原创性”男性和“刻板印象”女性。在α3波段，我们观察到皮层内相互作用模式的水平和特征变化的形成，这对每个组来说都是特定的，并且与受试个体的性别和答案的原创性水平有关。
