目前的研究探讨了与双语者用于解决竞争反应之间的干扰的局部和全局抑制过程相关的神经。两组参与者在接受功能性磁共振成像（fMRI）时完成了封闭和混合图片命名任务。一组先在L1中命名一组图片，然后在L2中命名相同的图片。另一组首先在L2中命名图片，然后在L1中命名。在阻塞命名任务之后，两组都执行了混合语言命名任务（即，根据提示以任一种语言命名图片）。在组间折叠的阻塞和混合命名任务之间的比较被定义为局部转换效应，而在每种语言中阻塞命名之间的比较被定义为全局转换效应。在双语单词产生中，局部抑制与全局抑制相比，发现了不同的神经激活模式。具体而言，结果表明，背侧前扣带皮层（ACC）和补充运动区（SMA）在局部抑制中起重要作用，而背侧左额回和顶叶皮层是重要的全局抑制。
The current study examined the neural correlates associated with local and global inhibitory processes used by bilinguals to resolve interference between competing responses. Two groups of participants completed both blocked and mixed picture naming tasks while undergoing functional magnetic resonance imaging (fMRI). One group first named a set of pictures in L1, and then named the same pictures in L2. The other group first named pictures in L2, and then in L1. After the blocked naming tasks, both groups performed a mixed language naming task (i.e., naming pictures in either language according to a cue). The comparison between the blocked and mixed naming tasks, collapsed across groups, was defined as the local switching effect, while the comparison between blocked naming in each language was defined as the global switching effect. Distinct patterns of neural activation were found for local inhibition as compared to global inhibition in bilingual word production. Specifically, the results suggest that the dorsal anterior cingulate cortex (ACC) and the supplementary motor area (SMA) play important roles in local inhibition, while the dorsal left frontal gyrus and parietal cortex are important for global inhibition.
