目前的研究表明，对受试者自己的名字（SON）的感知涉及多个多模态脑区，而单峰感觉区（即，初级听觉皮层）及其在自我加工过程中与多模态区域的相互作用仍不清楚。为了回答这个问题，我们结合多变量模式分析和动态因果模型分析来探索SON感知过程中的区域激活模式和区域间有效联系。我们发现SON和其他名字可以从初级听觉皮层的激活模式中解码出来。此外，我们发现SON对前额叶/额下回到初级听觉皮层和颞顶交界处的连接有兴奋作用。我们的研究结果扩展了目前自我处理的知识，表明初级听觉皮层可以区分SON和其他名字。此外，我们的研究结果强调了在自我处理过程中，大脑皮层对初级听觉皮层的影响的重要性。本研究结合多元模式分析和动态因果模型分析，探讨了被试对自己名字（SON）感知过程中的区域激活模式和区域间有效联系。我们的主要发现表明，SON和其他名字可以从初级听觉皮层的激活模式中解码。我们的研究结果扩展了目前自我处理的知识，表明初级听觉皮层可以区分SON和其他名字。
Current studies have shown that perception of subject's own name (SON) involves multiple multimodal brain regions, while activities in unimodal sensory regions (i.e., primary auditory cortex) and their interaction with multimodal regions during the self‐processing remain unclear. To answer this, we combined multivariate pattern analysis and dynamic causal modelling analysis to explore the regional activation pattern and inter‐region effective connection during the perception of SON. We found that SON and other names could be decoded from the activation pattern in the primary auditory cortex. In addition, we found an excitatory effect of SON on connections from the anterior insula/inferior frontal gyrus to the primary auditory cortex, and to the temporoparietal junction. Our findings extended the current knowledge of self‐processing by showing that primary auditory cortex could discriminate SON from other names. Furthermore, our findings highlighted the importance of influence of the insula on the primary auditory cortex during self‐processing. We combined multivariate pattern analysis and dynamic causal modelling analysis to explore the regional activation pattern and inter‐region effective connection during the perception of subject's own name (SON). Our main finding showed that SON and other names could be decoded from the activation pattern in the primary auditory cortex. Our findings extended the current knowledge of self‐processing by showing that primary auditory cortex could discriminate SON from other names.
