Several recent hypotheses of cerebral functional organization in natural left-handers hold that language, including reading, is localized either unilaterally in the left hemisphere or bilaterally, but not unilaterally in the right hemisphere. A case of alexia without agraphia in a left-hander with an infarct in the right occipital lobe and splenium of the corpus callosum is reported. That a permanent and complete alexia resulted from a single, right hemisphere lesion indicated that reading was completely lateralized to that hemisphere. The case demonstrates that in some natural left-handers language functions can be unilaterally represented in the right hemisphere.
最近一些关于天然左利手大脑功能组织的假说认为，包括阅读在内的语言功能要么单侧定位于左半球，要么双侧定位，但不会单侧定位于右半球。本文报告了一例左利手患者，其右枕叶和胼胝体压部梗死，出现失读症但无失写症。由单个右半球病变导致永久性完全失读症，这表明阅读功能完全定位于该半球。该病例表明，在一些天然左利手中，语言功能可以单侧定位于右半球。
