Paralyzing Facial Muscles with Botox May Make People Who Have

Paralyzing facial muscles with Botox may make people who have had the procedure less able to recognize emotional expressions in others. The explanation given for this finding is that:

A) Botox injections decrease activity in four brain areas (the anterior cingulate cortex, caudate nucleus, putamen, and insula) involved in interpreting emotions in other people.
B) feedback from our facial muscles helps us understand emotional expressions in others, and Botox prevents that from happening.
C) Botox injections to facial muscles can heighten emotional experiences, increase physiological arousal, and lessen our ability to pay attention to what others are feeling.
D) Botox injections affect brain areas, such as the amygdala, that regulate emotional experiences and lessen the ability to feel our own emotions as well as those of others.
