Starting about 200 ms after stimulus onset, words and pseudowords elicit differential cortical activation in normal healthy individuals. This early index of lexicality appears to be altered in stroke patients who have recovered from an aphasia. The talk discusses the possibility that word and pseudoword evoked potentials might indicate the restitution of language functions after stroke.
