论元结构，如动词词汇表征中的参与者角色，影响动词的加工。最近的神经影像学研究表明，当动词被听到或阅读时，后颞顶区显示出更大的激活动词与较低的论点结构复杂性，通常是双边的。此外，失语症患者表现出动词产生缺陷。根据论元结构的复杂性进行评分。在本研究中，我们使用功能磁共振成像检查的神经相关动词生产的公开行动命名条件。此外，我们测试了不同的效果命名时，动词动态地在视频片段与静态的线条画。结果表明，与不及物动词相比，不仅在后部区域，而且在左下额叶皮层，与及物动词的产生相关的神经元活动增加。我们还发现，与图片相比，视频中的传递性动作命名与不传递性动作命名在右下和上级顶叶皮层（与对象操作相关的区域）中的激活显著更大。这些研究结果表明，动词具有更大的论点结构密度产生分级激活的前部和后部的语言网络和支持动词命名赤字模式的病变研究报告。此外，视频和静态图片命名条件下得出的类似结果提供了使用视频在神经影像学研究，这是更自然的，也许生态有效性比使用静态图片调查动作命名的有效性。(C)2008爱思唯尔有限公司保留所有权利。
Argument structure, as in the participant roles entailed within the lexical representation of verbs, affects verb processing. Recent neuroimaging studies show that when verbs are heard or read, the posterior temporoparietal region shows increased activation for verbs with greater versus lesser argument structure complexity, usually bilaterally. In addition, patients with agrammatic aphasia show verb production deficits. graded bared on argument structure complexity. In the present study, we used fMRI to examine the neural correlates of verb production in overt action naming conditions. In addition, we tested the differential effects of naming when verbs were presented dynamically in video segments versus statically in line drawings. Results showed increased neuronal activity associated with production of transitive its compared to intransitive verbs not only in posterior regions, but also in left inferior frontal cortex. We also found significantly greater activation for transitive versus intransitive action naming for videos compared to pictures in the right inferior and superior parietal cortices, areas associated with object manipulation. These findings indicate that verbs with greater argument structure density engender graded activation of both anterior and posterior portions of the language network and support verb naming deficit patterns reported in lesion studies. In addition, the similar findings derived under video and static picture naming conditions provide validity for using videos in neuroimaging studies, which are more naturalistic and perhaps ecologically valid than using static pictures to investigate action naming.
