The facial feedback hypothesis is based on the idea that facial expression and emotional experience are linked.
​
Sensory feedback from the action of the facial muscles appears to influence an individual's emotional experience. Can the action of elevating your cheeks make you happier? Can the action of furrowing your brow make you angrier?
​
A study in 2014 by Kim et al., using functional MRI found that angry facial expressions increase the activity of the amygdala, which is the region of the brain primarily associated with emotional processing.
​
However, when the corrugator muscles (which furrow the brow) are paralyzed by Botox, there was a decrease in amygdalar activity. These are similar to previous findings showing that medication can result in decreased activity in the amygdala.
​
This suggests that Botox injections may block the emotional processing feedback loop to modulate psychological experience.
