Broca's area is known to be critically involved in language processing for more than 150 years. Recent neuroimaging techniques, including functional magnetic resonance imaging (fMRI) and diffusion MRI, enabled the subdivision of Broca's area based on both functional and anatomical aspects. Networks among the frontal association areas, especially the left inferior frontal gyrus (IFG), and other cortical regions in the temporal/parietal association areas, are also important for language-related information processing. Here, we review how neuroimaging studies, combined with research paradigms based on theoretical linguistics, have contributed to clarifying the critical roles of the left IFG in syntactic processing and those of language-related networks, including cortical and cerebellar regions.
150多年来，人们一直认为布洛卡区在语言处理中起着关键作用。最近的神经成像技术，包括功能磁共振成像（fMRI）和扩散磁共振成像，使得能够根据功能和解剖学方面对布洛卡区进行细分。额叶联合区之间的网络，尤其是左侧额下回（IFG），以及颞叶/顶叶联合区的其他皮质区域，对于语言相关信息处理也很重要。在这里，我们回顾神经成像研究如何与基于理论语言学的研究范式相结合，有助于阐明左侧额下回在句法处理中的关键作用以及语言相关网络（包括皮质和小脑区域）的关键作用。
