摘要
多人同步交互式记录是认知神经科学的一种新的研究范式, 它可以揭示两个或多个个体的大脑间在社交情境下神经活动的耦合。这一目标仅靠单个大脑活动的记录与测量是无法实现的。功能性近红外光谱成像在进行多人同步交互记录研究中有独特的优势。该方面的研究已经涵盖了社会认知神经科学的多个领域。本研究使用近红外光谱成像对社交情境下自我表露的双人大脑前额皮层的活动进行交互式测量, 并使用小波相关来分析双人大脑互动时的神经同步性。研究结果表明在进行社交对话时, 被试对的大脑间左侧额中回、右侧眶额皮层和右侧额下回下部的活动同步性显著增强。共情能力与社交情境下脑间同步性的强度呈正相关, 这种关系主要体现在右侧额下回。本研究支持了采用近红外光谱成像技术研究多人同步交互记录大脑间神经耦合的可行性和有效性。
Abstract
As a new research paradigm, hyperscanning is emerging from traditional methods of cognitive neuroscience. By simultaneously measure two or more individuals’ brain activities, hyperscanning can reveal the inter-brain synchronizations during the social interactions. Functional near-infrared spectroscopy (fNIRS), as a cost-effective, non-invasive and ecological optical brain imaging technique, has unique advantage in hyperscanning. By now, the fNIRS-based-hyperscanning has been used on various social interaction fields. In the present study, we applied fNIRS to hyper-scan two brains in the social context of self-disclosure. Wavelete coherence was used to analyze the inter-brain synchronization. Result showed that during the social dialogue, the coherences of two participants’ brain activities increase in the left middle frontal gyrus, the right orbitofrontal cortex and the right inferior frontal gyrus. Participants’ capacities of empathy were significantly positively correlated with the strength of brain inter-brain synchronization in the right inferior frontal gyrus. The present study provided evidence to support the feasibility of fNIRS for hyperscanning.
