Figure 1
A typical setup of an electroencephalography (EEG) hyperscanning during a card game. (a) The brain activity is simultaneously recorded from four subjects during the different rounds of the game. (b) Realistic models of the individual subjects’ heads, including scalp and cortical envelopes, are presented for each subject. The arrows depict the statistically significant connections estimated between the cortical areas of two members of a team during a phase of the game. The arrows start from a cortical region and point toward another cortical region. The causal links mean that the activity in the target cortical region can be better modeled by including the source region’s activity.

Figure 2
Distribution of the statistically significant differences in power spectra for the (a) cooperation and (b) defect conditions in the theta frequency band. We depict results on the average cortex model used in the study, seen from six different perspectives. The first row (from left to right) presents the brain cut sagittally, view from the right, then the cortical surface view from the left and the brain view from above, frontal part down. The second row shows the sagittal view of the cut brain from the left, the cortical surface from the right, and the frontal cortical areas. The grey areas indicate no statistically significant difference with respect to the rest period. The areas in color (from dark red to yellow) indicate a significant activation with respect to the rest. We only show activations common to at least 36 subjects.

Figure 3
Common patterns of the statistically significant functional connectivity links in the population of subjects when they decided to adopt (a) a pure-cooperative or (b) a pure-defect behavior. Such connectivity links describe parts of the brain in which the signals shared similar properties. All the represented links are statistically significant at p < 0.001, Bonferroni corrected for multiple comparisons. During the cooperative behavior, the pattern of functional connectivity links is much denser than in the defect situation.
