Abstract: Aphasia is one of the major complications after stroke, which needs an effective assessment. Event-related potential (ERP) has been widely researched in neurology, the endogenous components, such as P300, N400, mismatch negativity (MMN), contingent negative variation (CNV) have been widely used in diagnosis and evaluation of the impairment of brain function, including the language function. This paper discussed the application of different endogenous components of ERP in aphasia after stroke, especially the comparative analysis of N400 and P300.

Key words: stroke, aphasia, event-related potential, endogenous components, assessment
