尽管具有进化意义，但调节动态社会互动的神经机制仍未得到充分研究。交互式大脑假说提出，交互式社交线索是由专用的大脑基质处理的，并为研究社交互动的潜在神经机制提供了一个通用的理论框架。我们测试了这一假设的具体情况，提出在基于说话和倾听的社交互动过程中，规范语言区域在大脑中被上调并动态耦合。采用功能性近红外光谱 (fNIRS) 来获取合作伙伴大脑的同步脱氧血红蛋白 (deOxyHb) 信号，这些合作伙伴在自然环境中进行对象命名和描述任务时交替说话和聆听，无论是否有交互。交互和非交互条件的比较证实了交互期间与韦尼克区相关的神经活动增加，包括颞上回 (STG) (P = 0.04)。然而，布罗卡区的假设并未得到支持。通过对来自 STG 和次中心区域的信号进行小波分析确定的跨脑一致性在交互过程中比非交互过程中更大 (P < 0.01)。为了支持交互式大脑假说，这些发现表明了一种动态耦合的跨脑神经机制，专门用于共享人际信息的路径。
Neural mechanisms that mediate dynamic social interactions remain understudied despite their evolutionary significance. The interactive brain hypothesis proposes that interactive social cues are processed by dedicated brain substrates and provides a general theoretical framework for investigating the underlying neural mechanisms of social interaction. We test the specific case of this hypothesis proposing that canonical language areas are upregulated and dynamically coupled across brains during social interactions based on talking and listening. Functional near-infrared spectroscopy (fNIRS) was employed to acquire simultaneous deoxyhemoglobin (deOxyHb) signals of the brain on partners who alternated between speaking and listening while doing an Object Naming & Description task with and without interaction in a natural setting. Comparison of interactive and non-interactive conditions confirmed an increase in neural activity associated with Wernicke’s area including the superior temporal gyrus (STG) during interaction (P = 0.04). However, the hypothesis was not supported for Broca’s area. Cross-brain coherence determined by wavelet analyses of signals originating from the STG and the subcentral area was greater during interaction than non-interaction (P < 0.01). In support of the interactive brain hypothesis these findings suggest a dynamically coupled cross-brain neural mechanism dedicated to pathways that share interpersonal information.
