Dominance of the left hemisphere for many aspects of speech production and perception is one of the best known examples of functional hemispheric asymmetries in the human brain. ...
However, the strength of this correlation depends on the measures used to assess the two traits, and the neurophysiological basis of language lateralization is different from that of handedness. ...
A major challenge for the assumption that handedness and language lateralization have the same ontogenetic base comes from fTCD (functional transcranial Doppler sonography) and fMRI (functional magnetic ...
