近几十年来,Broca区和基底节之间的结构连接已经在文献中得到了假设,尽管还没有提供这种连接的直接证据。目前的研究使用一种新的扩散加权成像(DWI)纤维跟踪方法在人体活体内研究这种连接性。我们的发现表明,Broca区的亚区与壳核的前1/3以及丘脑的腹前核之间存在直接联系。因此,我们是第一个提供涉及基底节、丘脑和Broca区的推断回路的详细描述,这将是证实它们对语言处理的支持的先决条件。
In the recent decades structural connectivity between Broca's area and the basal ganglia has been postulated in the literature, though no direct evidence of this connectivity has yet been presented. The current study investigates this connectivity using a novel diffusion-weighted imaging (DWI) fiber tracking method in humans in vivo. Our findings suggest direct connections between sub-regions of Broca's area and the anterior one-third of the putamen, as well as the ventral anterior nucleus of the thalamus. Thus, we are the first to provide a detailed account of inferred circuitry involving basal ganglia, thalamus, and Broca's area, which would be a prerequisite to substantiate their support of language processing.
