Models of speaking distinguish producing meaning, words and syntax as three different linguistic components of speaking. Nevertheless, little is known about the brain's integrated neuronal infrastructure for speech production. We investigated semantic, lexical and syntactic aspects of speaking using fMRI. In a picture description task, we manipulated repetition of sentence meaning, words, and syntax separately. By investigating brain areas showing response adaptation to repetition of each of these sentence properties, we disentangle the neuronal infrastructure for these processes. We demonstrate that semantic, lexical and syntactic processes are carried out in partly overlapping and partly distinct brain networks and show that the classic left-hemispheric dominance for language is present for syntax but not semantics.
说话模型将表达意义、单词和语法区分成说话的三个不同语言成分。然而，对于大脑用于言语产生的综合神经结构却知之甚少。我们使用 fMRI 研究了言语的语义、词汇和句法方面。在图片描述任务中，我们分别操纵句子意义、单词和句法的重复。通过研究对这些句子属性重复的每种属性的大脑区域显示出响应适应性，我们分离出这些过程的神经元基础。我们证明语义、词汇和句法过程是在部分重叠和部分不同的大脑网络中进行的，并表明语言的经典左半球优势存在于句法而不是语义中。
