The present study examined linguistic plastic reorganization of language through Evoked Potentials
in a group of 17 non-fluent aphasic patients who had suffered left perisylvian focal lesions, and
showed a good linguistic recovery. Language reorganisation was probed with three linguistic
tasks (Phonological, Semantic, Orthographic), the early word recognition potential (N150) and the
later phonological-related component (N350). Results showed the typical left-lateralised posterior
N150 in healthy controls (source: left Fusiform Gyrus), that was bilateral (Semantic) or right sided
(Phonological task) in patients (sources: right Inferior/Middle Temporal and Fusiform Gyri). As regards
N350, controls revealed different intra- and inter-hemispheric linguistic activation across linguistic
tasks, whereas patients exhibited greater activity in left intact sites, anterior and posterior to the
damaged area, in all tasks (sources: Superior Frontal Gyri). A comprehensive neurofunctional model
is presented, describing how complete intra- and inter-hemispheric reorganisation of the linguistic
networks occurs after aphasic damage in the strategically dominant left perisylvian linguistic centres
