The main objective of this study was to investigate the relationship between the microstructural properties of
language-related white matter (WM) tracts and hand preference in typically
developing school-aged children. Our DTI tractography
results provide evidence for a different structural connectivity pattern of the
language connectome in left-handed children. Whereas right-handed children show a clear left-lateralized structural
language network, our group of left-handed children seems to have a more
bilateral organized language system. Those observed differences in WM
microstructure and lateralization might reflect an interaction between
handedness and the neural processing of language in children.
