Functional neuroimaging studies show that a set of brain areas, such as the fusiform gyrus and amygdala, become active when viewing emotional facial expressions. The majority of functional magnetic resonance imaging (fMRI) studies investigating face perception typically employ static images of faces.
How are facial emotions processed?
The researchers found that there are two groups of neurons in the amygdala that respond to facial emotions. One group, the emotion-tracking neurons, detects the intensity of a single specific emotion, such as happiness or fear.
What part of the brain controls facial movement?

What brain structure detects emotional significance of facial expressions?

What happens if you lose the right side of your brain?
