| Abstract | The left temporal lobe contains the regions crucial for language processing, such as Wernicke's area and surroundings, a part of arcuate fasciculus, and the anterior temporal lobe. The damage to one of these regions results in a specific aphasic syndrome which is accompanied by a unique type of alexia and agraphia. In addition, the left angular gyrus had been plausible candidate for critical region of pure alexia and agraphia. However, many Japanese researchers have shown that the posterior part of the left inferior temporal gyrus damage develops Kanji (morphogram) impairment. Subsequently, the researchers in English-speaking world have proposed the idea of "the visual word form area" which seems to be responsible for lexical alexia and agraphia. Dual-route cascaded model of reading and writing in Japanese has been proposed to explain the dissociated alexia and agraphia in Kanji and Kana. |
