We have read Dr Winterling's comments with appreciation. The speculation we offered relating original Chinese language experience to crossed aphasia must be viewed with caution as only one possible factor among others. We stated that this linguistic factor could not be the unique one for the same reason offered by Dr Winterling—namely, the paucity of cases of crossed aphasia in Chinese patients or any other patient group. His reference to the article in Science1 is relevant in showing that the incidence of righthandedness in Chinese is not significantly different from that in Caucasians. In any individual, multiple factors—genetic, pathologic, and others—are probably responsible for determining specific cerebral organization of speech-language functions and handedness.Even though differences in cognitive experience have been correlated with structural and functional properties of developing cortical neurons in the cat visual system,2 one can only speculate about possible relationships between early language experience
