我们研究了大脑活动在6个正常志愿者使用PET探索的假设，即右半球有一个特定的作用，在解释比喻方面的语言，如隐喻。我们还绘制了与句子理解有关的解剖结构。在局部脑血流量测量过程中，受试者被要求执行三种不同的语言任务：（i）隐喻理解;（ii）句子的字面理解;和（iii）词汇决策任务。我们发现，与词汇判断任务相比，句子的理解引起了左半球几个区域的广泛激活，包括前额叶和基底额叶皮层，颞中回和颞下回和颞极，顶叶皮层和楔前叶。对隐喻的理解与左半球的类似激活有关，但除此之外，右半球的一些部位也被激活：前额叶皮层、颞中回、楔前叶和后扣带回。我们的结论是，语言的解释涉及广泛的分布式系统双边与右半球具有特殊的作用，在欣赏隐喻。
We investigated cerebral activity in six normal volunteers using PET to explore the hypothesis that the right hemisphere has a specific role in the interpretation of figurative aspects of language such as metaphors. WE also mapped the anatomical structures involved in sentence comprehension. During regional cerebral blood flow measurement subjects were asked to perform three different linguistic tasks: (i) metaphorical comprehension; (ii) literal comprehension of sentences; and (iii) a lexical-decision task. We found that comprehension of sentences compared with the lexical-decision task induced extensive activation in several regions of The left hemisphere, including the prefrontal and basal frontal cortex, the middle and inferior temporal gyri and temporal pole, the parietal cortex and the precuneus. Comprehension of metaphors was associated with similar activations in the left hemisphere, but in addition, a number of sites were activated in the right hemisphere: the prefrontal cortex, the middle temporal gyrus, the precuneus and the posterior cingulate. We conclude that the interpretation of language involves widespread distributed systems bilaterally with the right hemisphere having a special role in the appreciation of metaphors.
