↵^a Number and proportion of electrodes with significant phase–amplitude coupling (PAC), measured using the z-scored modulation index (MIz) or the GLM framework (RPAC) during either the baseline or voice-onset interval.
↵^b The mean change (Δ) in PAC (MIz or RPAC ) per electrode between the baseline and voice-onset intervals (i.e., baseline minus voice onset). preCG, precentral gyrus; postCG, postcentral gyrus; pIFG, posterior inferior frontal gyrus.
