EEG hyperscanning study of team neurodynamics analysis during cooperative and competitive interaction

This paper analyzes team-neurodynamics during cooperative and competitive human interaction with EEG. Inter-brain synchrony was analyzed by different functional connectivity measurements between dyads during computer-based pong game, which imitated cooperative and competitive interaction. 18 dyads attended this experiment. Results show that mutual information is very sensitive to noise, power-correlation is the least noise-sensitive method. Intra-brain neural synchrony shows prefrontal and parastriatel were highly activated during cooperation and competition; inter-brain synchrony during cooperation is slightly stronger than the competition.
