Laterality indices (LI) for the inferior frontal gyrus (IFG, black bars) and the posterior portion of the superior temporal gyrus (pSTG, gray bars) of subject 8. Left panel indicates LIs from language tasks, right panel indicates LIs from music contrasts. An LI with an absolute value greater than 0.1 is defined as asymmetric where positive values (upward) indicate leftward-asymmetry and negative values (downward) indicate rightward-asymmetry. Both language and music contrasts resulted in leftward-asymmetry in IFG; however, pSTG demonstrated leftward-asymmetry for language contrast, but rightward-asymmetry for music tasks.
