Entrainment

I found this concept a couple of days ago:

“Entrainment is an important characteristic of interactions between brain rhythms and refers to the coupling of two independent oscillatory systems in such a way that their periods of oscillation become related by virtue of phase alignment (Cummins, 2009).”

And it makes me think how this could be converted into a tool that would portray the connection between two people in an obvious, visual way. Is there a path to literally visualizing our connections with other living beings?
