Subtle language in patients with stroke

© 2018 El Also of relevance for the study of the respective roles of each of the cerebral hemisphere are the not so rare cases of crossed aphasia (more frequent though among children!). The hypothesis of the « progressive transfer » (in the learning period) from the right hemisphere to the left of some components of the language faculty (together with other functions such as music. . .) will be put forward during the presentation, following the initial writings from Goldberg & Costa at the beginning of the eighties. Thus, the functional specificity of both hemispheres would not be considered as « hardwired » from the crib (and even before) for language, music. . . but would rather be the consequence of the processing (and evoluting) mode applied to such cognitive abilities as language, music, face recognition. . .. If correct, according to such a view, it would not be language or music that would be localized in the left or the right hemisphere but certain types of cognitive processes, as also shown by case studies of « split brain » patients as well as several studies on nonhuman primates.
