“…Right hemisphere frontal areas offer resources to maintain language function and this points to the high likelihood of a pre-existing language network in the right hemisphere that can be recruited when needed (Perani et al, 2003;Voets et al, 2006;Winhuisen et al, 2005). For example, a number of reports indicate that language dominance shifts to homologous righthemisphere regions following a disabling left hemisphere brain injury (Lazar et al, 2000;Staudt et al, 2002;Tivarus et al, 2012). However, the role of the right insula in language processing requires further study to determine its specificity of function as the activation could be related to other cognitive processes subserving irrelevant task features.…”

“…In these cases, the right hemisphere has partially taken over. 44,91 In general, recovery is more successful if the injury has slowly evolved. 15,94 The clinical gold standard for assessment of language dominance remains the amobarbital test, although this technique can be disputed on methodological and practical grounds.…”

“…18 Transcallosal reorganization is often seen in such cases with involvement of right hemispheric cortical regions that are homotopic to the left hemispheric regions involved in language processing under normal conditions, with resultant normal language function, though subtle deficits in certain nonlanguage functions (eg, visuospatial processing) generally represented in the right hemisphere have been noted in some individuals on neuropsychological testing. 18,19 Lidzba et al 20 have even suggested that verbal and nonverbal tasks are mediated not only within the same right hemisphere but also within the same network of the right hemisphere. This likely accounts for the fact that while normal right hemisphericϪlateralized language function is not associated with deficits of visuospatial processing, right hemispheric language representation occurring as a result of a left hemispheric lesion may be associated with such deficits, likely on the basis of the "crowding hypothesis," which refers to dominance of certain functions within a common right hemispheric functional network.…”
