Here we indirectly investigated peripheral vs. central processing of dissonance in music. Results showed a role of both peripheral and central mechanisms in the pleasantness percept of dichotic dissonance in music. Substantial between participant variations in binaural integration of dichotic dissonance in a VBM analysis related to grey matter density differences in the inferior colliculus (IC), which strongly substantiates a key role of the IC in consonance/dissonance representation in humans.
