Great emphasis has been placed on the right hemisphere, due to its possible selective contribution, in the processing of metaphorical statements.
To describe the processing of metaphors in the case of a patient with transcortical motor aphasia, using specific tests for patients with encephalic injuries of the right hemisphere, and to contribute to the discussion on the inter-hemispheric relationships associated with this function.
A 54 year-old man with transcortical motor aphasia was evaluated three years after a left hemisphere stroke. The tasks of comprehension of metaphors were based on the subtest Metaphor Comprehension Task of the Montreal Evaluation of Communications Scale (MEC). Two metaphor comprehension tests were applied, in 45-minute sessions with a 48 hour interval between each. Test 1 involved comprehension of the metaphors according to the options offered, and Test 2 the comprehension of metaphors measured by response time and visual field.
Although the right hemisphere was not affected by the stroke in this case, difficulties were observed in the processing of metaphors.
This study suggests that the left hemisphere participates in the processing of figurative meanings. The adaptability of the brain can also re-accommodate the uninjured areas of the brain, causing the dynamic of the brain to be modified. As a result, deducing cerebral functions based on clinical data can be problematic. The value of this study is that it can contribute to clinical aspects of language rehabilitation.
由于右半球在隐喻语句处理中可能具有选择性贡献，因此受到了极大关注。
通过对右半球脑损伤患者的特定测试，描述一名经皮质运动性失语症患者的隐喻处理情况，并为有关与此功能相关的半球间关系的讨论做出贡献。
一名54岁经皮质运动性失语症男性患者在左半球中风三年后接受评估。隐喻理解任务基于蒙特利尔交流量表（MEC）的子测试“隐喻理解任务”。应用了两项隐喻理解测试，每次测试时长45分钟，两次测试间隔48小时。测试1涉及根据提供的选项理解隐喻，测试2涉及通过反应时间和视野测量来理解隐喻。
尽管该病例中右半球未受中风影响，但在隐喻处理方面仍观察到困难。
本研究表明左半球参与了比喻意义的处理。大脑的适应性也可以重新调整大脑未受损区域，从而改变大脑的动态。因此，基于临床数据推断脑功能可能存在问题。本研究的价值在于它可为语言康复的临床方面做出贡献。
