Neurophysiological changes induced by intensive language action therapy in chronic aphasic participants. A brain potential elicited by written words at a latency of ∼250 ms increased significantly over a short therapy period. No comparable change was seen for meaningless pseudowords. The word-specific increase of this “Aphasia Recovery Potential” correlated with the improvement on a clinical language test and its sources were localised in both cortical hemispheres (after Pulvermüller et al., 2005b).
