What's in a Smile?

Interesting article in the New York Times about when and how we interpret smiles. A short excerpt from the article:

people recognize smiles by mimicking them. When a smiling person locks eyes with another person, the viewer unknowingly mimics a smile as well. In their new paper, Dr. Niedenthal and her colleagues point to a number of studies indicating that this imitation activates many of the same regions of the brain that are active in the smiler.

A happy smile, for example, is accompanied by activity in the brain’s reward circuits, and looking at a happy smile can excite those circuits as well. Mimicking a friendly smile produces a different pattern of brain activity. It activates a region of the brain called the orbitofrontal cortex, which distinguishes feelings for people with whom we have a close relationship from others. The orbitofrontal cortex becomes active when parents see their own babies smile, for example, but not other babies.

So, smiling at each other does lead to positive feelings. Growing Smiles recommends plenty of them! To read more from the article, follow the link here.
