句法（句子形式）和语义（句子意义）之间的区别是我们思考语言的基础。这种区别是否以及在哪里表现在神经水平上仍然是一个相当有争议的问题。在目前的功能磁共振成像研究中，我们研究了神经相关的句法和语义功能，使用一种创新的激活范式，专门设计来明确地解开句法从词汇语义方面的句子处理。我们的研究结果强烈表明，布罗卡区的一部分（BA 44，部盖）是至关重要的参与处理句法信息，而左额下回的下部（BA 47，部眶）是有选择地参与处理句子的语义方面。
The distinction between syntax (sentence form) and semantics (sentence meaning) is fundamental to our thinking about language. Whether and where this distinction is represented at the neural level is still a matter of considerable debate. In the present fMRI study, we examined the neural correlates of syntactic and semantic functions using an innovative activation paradigm specifically designed to unequivocally disentangle syntactic from lexicosemantic aspects of sentence processing. Our findings strongly indicate that a part of Broca's area (BA 44, pars opercularis) is critically implicated in processing syntactic information, whereas the lower portion of the left inferior frontal gyrus (BA 47, pars orbitalis) is selectively involved in processing the semantic aspects of a sentence.
