The ECD locations of the N1m responses in the anterior-posterior and superior-inferior dimensions. These were located in a restricted cortical area in both the left and the right hemisphere. The ECDs for the vowels with periodic (/a/ per & /u/ per ) excitation were anterior to those for aperiodic (/a/ aper & /u/ aper ) and tonal (/a/ tone & /u/ tone ) excitation. Bars indicate standard error of the mean.
