Villar-Rodríguez E, Palomar-García MA, Hernández M, et al. - Since the improvement of hemispheric language dominance takes place over several years, this research examined whether musicianship could increase the probability of observing right language dominance in left-handers. The outcomes revealed that atypical lateralization was more predominant in musicians (40%) than in nonmusicians (5%) using a classic fMRI language paradigm. In healthy left-handed individuals, the study found that musicianship is the first known factor related to a higher prevalence of atypical language dominance. The data demonstrated that differences in the frontal and temporal cortex might act as shared predisposing factors to both musicianship and atypical language lateralization.
