Music processing and right hemispheric language lateralization share a common network in the right auditory cortex and its frontal connections. Given that the development of hemispheric language dominance takes place over several years, this study
tested whether musicianship could increase the probability of observing right language dominance in left-handers. Using a classic fMRI language paradigm, results
showed that atypical lateralization was more predominant in musicians (40%) than in
nonmusicians (5%). Comparison of left-handers with typical left and atypical right lateralization revealed that: (a) atypical cases presented a thicker right pars triangularis
and more gyrified left Heschl's gyrus; and (b) the right pars triangularis of atypical
cases showed a stronger intra-hemispheric functional connectivity with the right
angular gyrus, but a weaker interhemispheric functional connectivity with part of the
left Broca's area. Thus, musicianship is the first known factor related to a higher prevalence of atypical language dominance in healthy left-handed individuals. We suggest
that differences in the frontal and temporal cortex might act as shared predisposing
factors to both musicianship and atypical language lateralization. [-]
