Abstract
Performing music at a professional level requires the integration of multimodal sensory and motor information and precise monitoring of the performance via auditory feedback. In the context of Western classical music, musicians are forced to reproduce highly controlled movements almost perfectly with a high reliability. These specialised sensorimotor skills are acquired during extensive training periods over many years. The superior skills of musicians are mirrored in functional and structural plastic adaptations of sensorimotor and auditory systems of the brain. Auditory-sensorimotor integration, for example, is accompanied by rapid modulations of neuronal connectivity in the time range of 20 minutes. Finally, dysfunctional plasticity in musicians, known as musician's dystonia, leads to deterioration of extensively trained fine motor skills. Musician's dystonia may be caused by training induced dysplasticity with pathological fusion of central nervous representations in sensorimotor cortical and subcortical brain regions.
