角回被认为是读写功能的关键区域。在最近的 PET（正电子发射形貌）激活研究中，角回在读写中的作用被重新估计。角回对于阅读和写作是否是必需的，目前正在讨论中，应该在临床上进行修正。我们经历过一例由于左侧枕叶回再次梗死而导致古典失读症和假名失写的病例。这个案例表明，日语假名中的失写症比汉字中的失读症更为明显。有趣的是，在左角回第一次脑梗塞时，没有发现更高的皮质功能障碍，而左角回被认为是失读症的关键区域。本案例支持了指出左枕回对日语假名阅读重要性的观点。
The angular gyrus has been proposed as the key area of reading and writing function. In recent PET (positron emission topography) activation studies, role of angular gyrus in the reading and writing has been reestimated. Whether the angular gyrus is necessary for reading and writing or not is now under discussion and should be clinically revised. We experienced a case that presented classical alexia with agraphia of kana (Japanese syllabogram) caused by the re-infarct in left lateral occipital gyrus. This case showed the alexia with agraphia more apparent in Japanese kana than in kanji characters. Interestingly, no higher cortical dysfunction was revealed at the first cerebral infarction in left angular gyrus which was assumed as the key area for alexia with agraphia. This case supported the opinion which pointed out the importance of left occipital gyrus on Japanese kana reading.
