Features of Functional Brain Connectivity in Children during Solving Cognitive Tasks

The results of an analysis of phase synchronization of theta brain activity in children when solving problems that involved computational abilities, visual search, and short-term operating memory have been presented. Functional connectivity within the temporal, frontal, central, and occipital-parietal areas of the cerebral cortex using EEG data has been calculated. Significant differences in the dynamics of synchronization of neuronal structures in the frequency range of the theta rhythm, both depending on the brain area and the type of performed task have been found. Significant increases in functional connectivity within prefrontal and temporal regions during visual search tasks have been found.
