| summary | 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 behaviour and neural activation. In this paper, we present the results of the simultaneous neuroelectric recording of 26 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. Functional connectivity links estimated by using Partial Directed Coherence reveal a common pattern of connectivity between frontal cortical regions when the subjects are coordinated in a common cooperative behaviour. A lack of functional connectivity were instead observed between the two subjects when a simultaneous defect was performed. |
