Blink it to sync it: Experimental evidence of synchronization of human brainwaves subjected to common photic forcing

In an effort to achieve synchronization in mesoscopic cortical activities, experiments were conducted on five individuals. An indirect coupling was established between the subjects via a common photic forcing. The results point to partial synchronization between intra- as well as inter-participant activities when subjected to common periodic photic stimulus. To investigate the possible mechanism, delayed correlations were computed. The constancy of phase shifts from these correlations, estimated by effective order parameter, suggests that partial phase resetting is the underlying mechanism.
