摘要：Objective: The language control network is vital among language-related networks responsible for solving the problem of multiple language switching. Researchers have expressed concerns about the instability of the language control network when exposed to external influences (e.g., Long-term second language learning). However, some studies have suggested that the language control network is stable. Therefore, whether the language control network is stable or not remains unclear.
Methods: In the present study, we directly evaluated the stability and instability of the language control network using resting-state functional magnetic resonance imaging (rs-fMRI). We employed cohorts of Chinese first-year college students majoring in English who underwent second language (L2) acquisition courses at a university and those who did not. Two resting-state fMRI scans were acquired approximately 1 year apart. We found that the language control network was both moderately stable and unstable. We further investigated the morphological coexistence patterns of stability and instability within the language control network. First, we extracted connections representing stability and plasticity from the entire network. We then evaluated whether the coexistence patterns were modular (stability and instability involve different brain regions) or non-modular (stability and plasticity involve the same brain regions but have unique connectivity patterns).
Results: We found that both stability and instability coexisted in a non-modular pattern. Compared with the non-English major group, the English major group has a more non-modular coexistence pattern.
Limitations: This study spanned a wide range of practices, and the sources of variation in the linguistic control network could not be precisely controlled to ensure that the values were derived from bilingual experience.
Conclusions: These findings provide preliminary evidence of the coexistence of stability and instability in the language control network.

摘要：宗族是以血缘关系为基础的、强调家族内部统治秩序的社会组织实体。宗族文化以血脉为纽带，重视维护族内成员的关系，同宗同族是身份认同的关键所在。宗族观念包括血缘认同、互助、孝道、传承、礼治和乡土观念，体现了宗族成员对家族重要性和角色的内在信仰和态度。宗族观念和宗族文化相互依存，共同作用，影响着人们的行为和价值观，对现代社会的发展具有深远影响。
