The analysis of local and spatial alpha-activity synchronization in males and females with rigid and flexible cognitive style under conditions of rest state and during solving of convergent and divergent tasks was conducted. It was shown, that males have more expressed processes of local and spatial synchronization, related to cognitive style in comparison to females. Males with rigid and flexible cognitive styles had have different expression of effect of spatial synchronization lowering during cognitive activity: “flexible” males have this effect during first task (convergent task), “rigid” – during second task (divergent task). During solving the divergent task males with flexible cognitive style have increase in quantity of coherent connections between frontal lobes, more expressed in left hemisphere, males with rigid cognitive style have decrease in quantity of coherent connections in posterior areas, more expressed in right hemisphere. Moreover, the males with flexible cognitive style were noticed to have the lower activation of right hemisphere areas via alpha-activity power increase. The females have statistically significant differences related only to the level of interaction between temporal and parietal areas.
