Critically, a pronounced functional asymmetry was observed due to a stronger activation of the trained as compared with the untrained hemisphere indexed by significant Trained hemisphere x Laterality interactions for α 2 (F(1/45) = 9.3, p = 0.004) and β bands (F(1/45) = 11.05, p = 0.002), and a marginally significant interaction for α 1 (F(1/45) = 3.3, p = 0.07).
