利手对语言处理的影响已经被广泛研究，结果表明这两个变量之间存在关系;然而，这种关系的性质并不清楚。在目前的研究中，我们探讨了程度的利手（DH）反对的方向，在一组右撇子的个人。采用fMRI技术研究DH对句子理解网络的影响。结果显示，在句子理解过程中，与语义记忆相关的区域（例如，前颞叶皮层）由DH调制。此外，意外的是，与情节记忆有关的楔前叶/后扣带回也受到DH的影响。这些结果扩展了以前报道的那些显示，支持句子理解的神经结构是由DH调制。更具体地说，本文的研究结果支持了汤森、卡里瑟斯和贝弗（2001）提出的假设，即DH与语言系统相互作用，影响句子理解过程中使用的策略。
The impact of handedness on language processing has been studied extensively and the results indicate that there is a relationship between the two variables; however, the nature of the relationship is not at all clear. In the current study we explored degree of handedness (DH) opposed to direction in a group of right-handed individuals. fMRI was used to explore the impact of DH on the sentence comprehension network. The results revealed that during sentence comprehension activation in regions linked to semantic memory (e.g., anterior temporal cortex) were modulated by DH. Also, unexpectedly the precuneus/posterior cingulate gyrus which has been linked to episodic memory was also affected by DH. These results extend those reported previously by showing that the neural architecture that supports sentence comprehension is modulated by DH. More specifically, together the results presented here support the hypothesis proposed by Townsend, Carrithers, and Bever (2001) that DH interacts with the language system and impacts the strategy used during sentence comprehension.
