Factor 240 corresponded to N2 sink amplitude for targets, which showed a marked task-dependent topography of this component: it was most prominent over frontocentral sites for tones, with a modest shift toward the right hemisphere, whereas it was greatest over left lateral temporoparietal sites for syllables (Figure 3B, row 3). To adequately represent the task-dependent topographic specificity of this component, two separate ANOVA were computed using three homologous pairs over frontocentral (F3/4, FC5/6, C3/4) or temporo-parietal (P7/8, P9/10, TP9/10) regions.
