算术和语言处理涉及类似的神经网络，但相对参与仍不清楚。在本研究中，我们使用fMRI来比较语音、乘法和减法任务的激活，保持刺激材料的恒定，在一个预先定义的语言计算网络中，包括左额下回和角回(AG)以及双侧顶上小叶和顶内沟。结果显示，语音的语言计算网络中的激活模式总体上是左侧的，算术的激活模式是双侧的，并提示了任务之间的区域差异。特别是，我们发现语音在左下额下回的盖部中的作用比算术更显著，而在三角回中则具有领域共性。顶叶激活模式显示视觉和数量系统比语言更多地参与计算。这组发现支持了一个共同的、但在地区上有差异的语言计算网络的概念。(C)2015年提交人。由爱思唯尔公司出版。
Arithmetic and language processing involve similar neural networks, but the relative engagement remains unclear. In the present study we used fMRI to compare activation for phonological, multiplication and subtraction tasks, keeping the stimulus material constant, within a predefined language-calculation network including left inferior frontal gyrus and angular gyrus (AG) as well as superior parietal lobule and the intraparietal sulcus bilaterally. Results revealed a generally left lateralized activation pattern within the language-calculation network for phonology and a bilateral activation pattern for arithmetic, and suggested regional differences between tasks. In particular, we found a more prominent role for phonology than arithmetic in pars opercularis of the left inferior frontal gyrus but domain generality in pars triangularis. Parietal activation patterns demonstrated greater engagement of the visual and quantity systems for calculation than language. This set of findings supports the notion of a common, but regionally differentiated, language-calculation network. (C) 2015 The Authors. Published by Elsevier Inc.
