TITLE:
Musicianship modulates the relation between cortex volume and mismatch negativity amplitude to sound deviants.
ABSTRACT:
Mismatch negativity (MMN) is a widely studied component of the event-related potential elicited by a deviant stimulus inserted in a sequence of coherent ones. Previous literature showed that MMN amplitude is modulated by individual differences along musical expertise and psychological features such as depression trait, working memory abilities and fruition of music.
Using advanced techniques as fMRI and MEG, several studies explored brain morphologic structures and functions, investigating similarities, differences and interactions between them.
In our study, we show the relation between cerebral cortex volume and MMN amplitude to sound deviants, revealing a strong significant association in participants without musical expertise. Interestingly, musicians did not exhibit any connection between cortex volume and MMN amplitude. These results might signify that MMN amplitude to sound deviants is originally dependent on the cerebral cortex volume, but that a long-term musical training is able to nullify this relation.
