Outline of Final Research Achievements

We investigated the mechanisms of the lexical error reading in aphasia after brain damage. 21 aphasic patient and normal people with no brain damage read real words and non-words. In spite of reading aloud, we tested whether they understand the non-words as non-words by pointing task. It make clear that aphasic patients had more reading error in non-word reading task than normal people. Analysis of the site of lesion revealed that legion in the left precentral gyrus, inferior frontal gyrus and middle frontal gyrus and concerned with the lexical error reading.
