Recent neuropsychological studies have revealed that the processing of kanji (the Japanese morphograms) and kana (the Japanese syllabograms) involves different intrahemispheric mechanisms. We describe a patient showing left unilateral agraphia without apraxia for kanji, but not for kana, who was diagnosed by magnetic resonance imaging as having a lesion of the posterior body of the corpus callosum. This patient indicates that different neural pathways are used for kanji and kana not only intrahemispherically, but also interhemispherically.
