Grand average source waveforms of the responses to the stimuli. A–C, Native deviant (A; red), non-native deviant (B; green), and Standard (C; blue) are shown at left auditory cortex (LAC) in solid color line, at right auditory cortex (RAC) in small-dotted color line, and in the ACC in large-dotted color line. Positive is plotted up; strength of the source dipole moment is given in nanoampere meters (nAm) and latency in milliseconds (ms).
