  • Title: Effects of musical expertise on the early right anterior negativity: an event-related brain potential study.
    Author: Koelsch S, Schmidt BH, Kansok J.
    Journal: Psychophysiology; 2002 Sep; 39(5):657-63. PubMed ID: 12236333.
    Abstract:
    Event-related brain potentials in response to harmonically inappropriate chords were compared for musical experts and novices. Similar to previous studies, these chords elicited an early right anterior negativity (ERAN). The amplitude of the ERAN was clearly larger for musical experts than for novices, presumably because experts had more specific musical expectancies than novices. Chords with a physically deviant timbre elicited a mismatch negativity that did not differentiate the groups, indicating that the larger ERAN in experts was not due to a general enhanced auditory sensitivity. The ERAN reflects fast and automatic neural mechanisms that process complex musical (music-syntactic) irregularities, and the present results indicate that these mechanisms can be modulated by expertise.
