Musical training leads to sensory and motor neuroplastic changes in the human brain. Motivated by findings on enlarged corpus callosum in musicians and asymmetric somatomotor representation in string players, we investigated the relationship between musical training, callosal anatomy, and interhemispheric functional symmetry during music listening. Functional symmetry was increased in musicians compared to nonmusicians, and in keyboardists compared to string players. This increased functional symmetry was prominent in visual and motor brain networks. Callosal size did not significantly differ between groups except for the posterior callosum in musicians compared to nonmusicians. We conclude that the distinctive postural and kinematic symmetry in instrument playing cross-modally shapes information processing in sensory-motor cortical areas during music listening. This crossmodal plasticity suggests that motor training affects music perception.

Coupling of Action-Perception Brain Networks during Musical Pulse Processing : Evidence from Region-of-Interest-Based Independent Component Analysis Burunat, Iballa; Tsatsishvili, Valeri; Brattico, Elvira; Toiviainen, Petri (Frontiers Research Foundation, 2017)Our sense of rhythm relies on orchestrated activity of several cerebral and cerebellar structures. Although functional connectivity studies have advanced our understanding of rhythm perception, this phenomenon has not ...
Hartmann, Martin; Toiviainen, Petri; Lartillot, Olivier (College of Music, Yonsei University, 2014)In the act of music listening, many people break down musical pieces into chunks such as verses and choruses. Recent work on music segmentation has shown that highly agreed segment boundaries are also considered strong ...
