Experiencing strong emotions synchronizes brain activity across individuals, a research team at Aalto University and Turku PET Centre in Finland has revealed.
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.
