我们进行了两个功能磁共振成像(FMRI)实验，以考察歌词知识和误解的神经基础。在fMRI实验1中，左脑语言相关区和双侧纹状体区对歌词的熟悉程度与激活之间存在线性关系，这与前人关于歌词生成的研究一致。在fMRI实验2中，我们使用所谓的Mondedeens和Soramimi来诱导对歌词的误解，这些歌词揭示了一个包括中额叶和下额叶以及前扣带皮质(ACC)和丘脑内侧的双侧网络。ACC的激活也与误解被判断为有趣的程度相关，证实了先前关于该区域在调节音乐感知过程中寒战愉快体验方面的神经成像结果。最后，我们使用弥散加权成像(DWI)检查了歌词错误感知过程中涉及的区域，以确定它们的结构连接性。这些联合的功能磁共振成像/弥散加权成像结果可以作为未来研究其他类型误解的神经生物学模型，这些误解是对我们的社会生活具有潜在强烈影响的事件。
We conducted two functional magnetic resonance imaging (fMRI) experiments to investigate the neural underpinnings of knowledge and misperception of lyrics. In fMRI experiment 1, a linear relationship between familiarity with lyrics and activation was found in left-hemispheric speech-related as well as bilateral striatal areas which is in line with previous research on generation of lyrics. In fMRI experiment 2, we employed so called Mondegreens and Soramimi to induce misperceptions of lyrics revealing a bilateral network including middle temporal and inferior frontal areas as well as anterior cingulate cortex (ACC) and mediodorsal thalamus. ACC activation also correlated with the extent to which misperceptions were judged as amusing corroborating previous neuroimaging results on the role of this area in mediating the pleasant experience of chills during music perception. Finally, we examined the areas engaged during misperception of lyrics using diffusion-weighted imaging (DWI) to determine their structural connectivity. These combined fMRI/DWI results could serve as a neurobiological model for future studies on other types of misunderstanding which are events with potentially strong impact on our social life.
