ASI in bipolar derivations. (A) Developmental changes in ASI computed from bipolar derivations for both interhemispheric and intrahemispheric channel combinations. Note that the correlation is often not significant and its strength (r) is smaller as compared to monopolar derivations (Fig. 3). (B) Hemispheric and anterior–posterior comparisons reveal significant asymmetries. Comparison of frontal and posterior interhemispheric connections shows frontal dominance in 20 out of 22 cases, while the left side shows stronger ASI in 16 out of 22 cases.
