<p>(A) Discrimination index as boxplots for the major third (white) and the fifth (gray). The difference is not significant (p > 0.05). (B) Individual MMN amplitude at Fz for the major third (white circle) and the fifth (black squares) as functions of the individual discrimination index d’.</p

<p><b>Grand average ERP waveforms as elicited by ‘standard’ (light gray line) and ‘deviant’ (dark gray line) <i>major third</i> (left) or <i>fifth</i> (right) intervals at Fz.</b> The black lines show the difference waveforms between the ‘deviant’ and ‘standard’ waveforms. The contour maps show the distribution of response polarities on an average scalp at the latency of the MMN. Clear fronto-central negativity is only evoked by the major third deviants.</p
