Abstract	In the article, occipital lobular lesions were the starting point of the discussion, and I discussed disorders of reading and writing caused by occipital lobular lesions, i.e., the failure of reading and writing systems in the occipital lobes. I considered that agraphia caused by occipital lobular lesions was associated with the lesion, which included the boundary between occipital and parietal lobes and that between occipital and temporal lobes. The lesion expanded to the angular gyrus in a parietal lobe, and lesions expanding to the middle and inferior temporal gyri could be associated with agraphia with alexia. Lesions separated from an occipital lobe and close to a parietal or temporal lobe could be associated with agraphia without alexia. Restricted occipital lobular lesions may be associated with pure alexia, and lesions expanding to a parietal or temporal lobe may accompany agraphia. Therefore, the boundary lesion in a temporal lobe around the middle and inferior temporal gyri and that in a parietal lobe around the angular gyrus are noteworthy. In addition, I mentioned topics concerning pure alexia: several recent reports about the visual word form area (VWFA), and the mechanisms of number and letter-by-letter reading.
