小品词是日语句子的重要组成部分。它们主要跟在名词之后，表示名词在句子中的主位角色，如施事或受事。本研究利用功能磁共振成像来研究颗粒加工的神经基础。当参与者被要求判断一个呈现的字符是否是一个粒子，或者该字符是否以特定的元音结尾时，我们比较了大脑活动。在粒子判断过程中，只在左额下回发现了不同的大脑活动。我们进一步证实，这种活动不是一般范畴判断的特征。我们的结果表明，左额下回参与了日语助词所指示的主题角色的加工。
Particles are a crucial component of sentences in Japanese. They mainly follow nouns, and indicate their thematic role in the sentence, such as agent or patient. This study used functional MRI to investigate the neural basis of the processing of particles. We compared brain activity when participants were required to judge whether a presented character was a particle or whether the character as spoken ended with a specific vowel sound. Differential brain activity during particle judgment was found only in the left inferior frontal gyrus. We further confirmed that this activity was not a feature of categorical judgments in general. Our results indicate that the left inferior frontal gyrus is involved in the processing of thematic role indicated by Japanese particles.
