Figure 4.

Across subjects mean (±standard error) event‐related coherence (ErCoh) values in the alpha 3 frequency band. Statistical results showed a significant interaction (P = 0.013) between the two factors (ECD pair and spectral overlap of CV‐syllables) indicating that, compared to sham DL, during DL (/da/‐/ba/) there was an inverse pattern of functional coupling: whereas interhemispheric high‐band alpha (alpha 3) ErCoh between left and right PAC was reduced, intrahemispheric high‐band alpha ErCoh within the left hemisphere (left PAC ↔ Wernicke's area) was increased.
