For left-handers, cognitive functions are organized in the brain similarly to right-handers or they are more diffusely represented. In this study, we report a left-handed patient with a focal right temporal-parietal lesion who evidenced a lasting Wernicke's aphasia and visual-spatial functioning typical of a right-hander with left-hemisphere in involvement. The patient's performance on other tasks (e.g. praxis, singing) as well as observed behavioral changes also resembled those of a right-hander with left-hemisphere compromise. This case suggests that it is possible for cognitive functions to be inversely represented in the two hemispheres.
对于左利手者而言,其大脑中的认知功能组织方式与右利手者相似,或者呈现出更分散的表征。在本研究中,我们报告了一名左利手患者,其右侧颞顶叶有局灶性病变,表现出持续的韦尼克失语症以及典型的右利手者左半球受累时的视觉空间功能。该患者在其他任务(如运用、唱歌)中的表现以及观察到的行为变化也类似于左半球受损的右利手者。该病例表明,认知功能在两个半球中逆向表征是有可能的。
