Root mean square data. Root mean square values reflecting overall signal strength in response to standards (black), pitch deviants (medium grey) and pattern deviants (light grey), and difference curves (pitch deviants – standards: medium grey; pattern deviants – standards: light grey) showing the MMN responses, for two individual subjects (one musician and one nonmusician, upper panels) and for group averages of musicians and nonmusicians (lower panels).
