How do brains shape social networks, and how do social ties shape the brain? Social networks are complex webs by which ideas spread among people. Brains comprise webs by which information is processed and transmitted among neural units. While brain activity and structure offer biological mechanisms for human behaviors, social networks offer external inducers or modulators of those behaviors. Together, these two axes represent fundamental contributors to human experience. Integrating foundational knowledge from social and developmental psychology and sociology on how individuals function within dyads, groups, and societies with recent advances in network neuroscience can offer new insights into both domains. Here, we use the example of how ideas and behaviors spread to illustrate the potential of multilayer network models.

大脑和社交网络：人类经验的基本组成部分

大脑如何塑造社交网络，社会关系又如何塑造大脑？社交网络是复杂的网络，思想通过它在人们之间传播。大脑由网络组成，信息通过网络在神经单元之间进行处理和传输。虽然大脑活动和结构为人类行为提供了生物机制，但社交网络为这些行为提供了外部诱导剂或调节剂。这两个轴共同代表了人类体验的基本贡献者。将社会和发展心理学以及社会学中关于个体如何在二元、群体和社会中发挥作用的基础知识与网络神经科学的最新进展相结合，可以为这两个领域提供新的见解。在这里，我们用思想和行为如何传播的例子来说明多层网络模型的潜力。
