Feeling Strong Emotions Makes Peoples' Brains 'Tick Together'

Human emotions are highly contagious. Seeing others' emotional expressions such as smiles triggers often the corresponding emotional response in the observer. Such synchronization of emotional states across individuals may support social interaction: When all group members share a common emotional state, their brains and bodies process the environment in a similar fashion.

Researchers at Aalto University and Turku PET Centre have now found that feeling strong emotions makes different individuals' brain activity literally synchronous.

The results revealed that especially feeling strong unpleasant emotions synchronized brain's emotion processing networks in the frontal and midline regions. On the contrary, experiencing highly arousing events synchronized activity in the networks supporting vision, attention and sense of touch.

"Sharing others' emotional states provides the observers a somatosensory and neural framework that facilitates understanding others' intentions and actions and allows to 'tune in' or 'sync' with them. Such automatic tuning facilitates social interaction and group processes," says Adjunct Professor Lauri Nummenmaa from the Aalto University, Finland.

I'll just add that consensus, which since the Enlightenment has been the basis of any legitimate government, literally means "to feel together". A consensus is literally when brains are synced together in the ways being described in this paper.

Here's a nice example of consensus behavior:
