In this study we measured simultaneously by EEG hyperscannings the neuroelectric activity in 6 couples of subjects during the performance of the "Chicken's game", derived from game theory. The simultaneous recording of the EEG in couples of interacting subjects allows to observe and model directly the neural signature of human interactions in order to understand the cerebral processes generating and generated by social cooperation or competition. Results suggested that the one of the most consistently activated structure in this particular social interaction paradigm is the left orbitofrontal cortex. Connectivity results also showed a significant involvement of the orbitofrontal regions of both hemispheres across the observed population. Taken together, results confirms that the study of the brain activities in humans during social interactions can take benefit from the simultaneous acquisition of brain activity during such interaction.
在本研究中，我们通过脑电图超扫描同时测量了6对受试者在进行源自博弈论的“斗鸡博弈”时的神经电活动。对相互作用的受试者对进行脑电图同步记录，有助于直接观察和模拟人类互动的神经特征，以便了解产生社会合作或竞争以及由社会合作或竞争所产生的大脑过程。结果表明，在这个特定的社会互动范式中，最持续激活的结构之一是左侧眶额皮质。连通性结果还显示，在观察的人群中，两个半球的眶额区域均有显著参与。综合来看，结果证实，在社会互动过程中对人类大脑活动的研究可以受益于在此类互动期间对大脑活动的同步采集。
