One of the most challenging questions open in Neuroscience today is the characterization of the brain responses during social interaction. A major limitation of the approaches used in most of the studies performed so far is that only one of the participating brains is measured each time. The "interaction" between cooperating, competing or communicating brains is thus not measured directly, but inferred by independent observations aggregated by cognitive models and assumptions that link behavior and neural activation. In this paper, we present the results of the simultaneous neuroelectric recording of 5 couples of subjects engaged in cooperative games (EEG hyperscanning). The simultaneous recordings of 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. We used a paradigm called Prisoner's dilemma derived from the game theory. Results collected in a population of 10 subjects suggested that the most consistently activated structure in social interaction paradigms is the orbitofrontal region (roughly described by the Brodmann area 10) during the condition of competition.
当今神经科学领域尚未解决的最具挑战性的问题之一，是对社交互动过程中大脑反应的特征描述。到目前为止，大多数研究所采用方法的一个主要局限性在于，每次仅对参与互动的大脑之一进行测量。因此，合作、竞争或交流的大脑之间的“互动”并非直接测量得出，而是通过认知模型和将行为与神经激活联系起来的假设所汇总的独立观察结果推断出来的。在本文中，我们展示了对5对参与合作游戏的受试者进行同步神经电记录（脑电图超扫描）的结果。对相互作用的受试者对进行同步记录，能够直接观察和模拟人类互动的神经特征，以便了解由社会合作或竞争产生以及产生社会合作或竞争的大脑过程。我们使用了一种源自博弈论的名为“囚徒困境”的范式。在10名受试者群体中收集的结果表明，在竞争条件下，社交互动范式中最持续激活的结构是眶额区域（大致由布罗德曼第10区描述）。
