在主语-宾语-动词(SOV)语言中，句子处理逐渐进行到中心语(动词)的后期呈现。日语格助词在句子处理中起着至关重要的作用，然而，人们对这些助词是如何处理的知之甚少。特别是，格助词之间的功能差异在人脑中是如何表现的，目前还不清楚。在这项研究中，我们使用事件相关设计进行了fMRI实验，以直接比较日语格助词加工过程中主格ga、宾格o和与格ni之间的脑活动。25名母语为日语的人被要求在助词判断任务中判断呈现的字是否是助词，并在语音判断任务中判断该字是否以特定的元音结尾，这被用作控制条件。颗粒比较显示，在左侧额中回(MFG)和额下回(IFG)，加工Ni的脑活动明显弱于ga和o。在右侧IFG中，也观察到了与ni相对ga相关的显著更大的脑活动。这些结果表明，日语格助词ga、ni和o在大脑中的表现有所不同。
In subject–object–verb (SOV) languages, such as Japanese, sentence processing proceeds incrementally to the late presentation of the head (verb). Japanese case particles play a crucial role in sentence processing; however, little is known about how these particles are processed. In particular, it is still unclear how the functional difference between case particles is represented in the human brain. In this study, we conducted an fMRI experiment using an event-related design to directly compare brain activity during Japanese case particle processing among the nominative case ga, accusative case o, and dative case ni. Twenty five native Japanese speakers were asked to judge whether the presented character was a particle in a particle judgment task and whether the character ended with a specific vowel in a phonological judgment task, which was used as a control condition. A particle comparison demonstrated that the processing of ni was associated with significantly weaker brain activity than that of ga and o in the left middle frontal gyrus (MFG) and the inferior frontal gyrus (IFG). Significantly greater brain activity associated with ni relative to ga in the right IFG was also observed. These results suggest that the Japanese case particles ga, ni, and o are represented differently in the brain.
