Japanese patients with alexia without aphasia caused by focal left hemispheric damage show the dissociation between Kanji and Kana. Recently discovered was that the patient with left posterior inferior temporal (PIT) lesion developed alexia without aphasia selective for Kanji. We carried out activation studies using H215O PET scan and confirmed the role of PIT area in semantic reading process. Although the role of left angular gyrus (AG) in reading process could not be confirmed by PET scan studies, the adjacent left lateral occipital area was found to be significantly activated in phonological reading process.
