title: Recovery from aphasia: a longitudinal study on language recovery, lateralization patterns, and attentional resources.
abstract: Despite the large body of evidence on the neural basis of the recovery from aphasia, the role of either cerebral hemisphere remains controversial. This paper reports the results of a longitudinal single-case study on the patterns of lateralization for lexical semantic processing during the recovery from aphasia. The experimental protocol included a lateralized lexical decision task (LDT), an attentional task and a language test. There was no presentation site effect on the LDT, and the performance was jointly influences by attentional and language factors. These findings suggest that the recovery of lexical semantic processing may be sustained by both cerebral hemispheres, and highlights the importance of experimental protocols that allow examining both language and attentional factors modulating factors modulating the recovery from aphasia.
