Abstract(in Japanese) (See Japanese page)
Abstract(in English) Dual neural circuit model of reading and writing explaining the dissociated alexia and agraphia in kanji and kana has been proposed by the present author. PET scan activation studies on the reading aloud processes of kanji and kana words were done in order to confirm the validity of this model. The results showed that the left posterior inferior temporal area was activated in reading kanji and kana words, while the left lateral occipital area was activated in kana word and kana no-word reading. No activation was seen in left inferior parietal lobule.
