Strength distribution of within- and between-phase interactions located over F brain regions: (A) within-phase interaction in Frontal (Fθ), (B) between-phase interaction in Frontal (Fθ-α2), (D) within-phase interaction in Parieto-Occipital (POα2), and (E) between-phase interaction in Parieto-Occipital (POθ-α2) and (C) cross-frequency coupling between them (F2 × θ – POα2) for both correct and wrong answers. Bars represent mean ± standard deviations. No statistical significant differences were detected between correct and wrong trials.
