Chinese, as a logographic language, fundamentally differs from alphabetic languages like English. Previous neuroimaging studies have mainly focused on alphabetic languages, while the exploration of Chinese reading is still an emerging and fast-growing research field. Recently, a growing number of neuroimaging studies have explored the neural circuit of Chinese reading. Here, we summarize previous research on Chinese reading from a connectomic perspective. Converging evidence indicates that the left middle frontal gyrus is a specialized hub region that connects the ventral with dorsal pathways for Chinese reading. Notably, the orthography-to-phonology and orthography-to-semantics mapping, mainly processed in the ventral pathway, are more specific during Chinese reading. Besides, in addition to the left-lateralized language-related regions, reading pathways in the right hemisphere also play an important role in Chinese reading. Throughout, we comprehensively review prior findings and emphasize several challenging issues to be explored in future work.
中文作为一种表意文字，与英语等字母文字在根本上有所不同。以前的神经影像学研究主要集中在字母语言上，而对中文阅读的探索仍然是一个新兴且快速发展的研究领域。最近，越来越多的神经影像学研究探索了中文阅读的神经回路。在这里，我们从连接组学的角度总结了以前关于中文阅读的研究。越来越多的证据表明，左侧额中回是一个专门的枢纽区域，连接了中文阅读的腹侧和背侧通路。值得注意的是，在中文阅读中，字形到语音和字形到语义的映射主要在腹侧通路中进行，并且更加具体。此外，除了左侧与语言相关的区域外，右半球的阅读通路在中文阅读中也起着重要作用。总的来说，我们全面回顾了先前的发现，并强调了未来工作中需要探索的几个具有挑战性的问题。
