“Scientists laid out a roadmap for multi-brain neurofeedback, a system that reads two or more people’s brainwaves at once and feeds the sync back live to help them connect, learn, and work together. The approach sorts that feedback into three levels: split-second signal matching, shared mental pictures, and the overall health of a group. More sync is not always better, since it can signal conformity or one voice dominating, so the authors say the tool may work best by tracking the shifts between connection and disconnection.”
