Extended Data Fig. 3: Validation of neural synchronization.
From: Leader–follower behavioural coordination and neural synchronization during intergroup conflict
(a) We generated pseudo groups by randomly grouping a real leader and two real followers from different original groups to a pseudo group. We then re-calculated neural synchronization of pseudo groups using the same method as we did for the real pairs. We repeated the generation of pseudo groups and recalculation of neural synchronization for 1000 times. We verified stronger neural synchronization in real interacting leader-follower pairs of defender groups than pseudo groups (b, p = 0.003), but not for follower-follower pairs of defender groups (c, p = 0.981), nor leader-follower (d, p = 0.711), follower-follower (e, p = 0.590) pairs of attacker groups.
