Facial muscle patterning to affective imagery in depressed and nondepressed subjects
Science (New York, N.Y.)
|April 30, 1976
Abstract:
When subjects imagine happy, sad, and angry situations, different patterns of facial muscle activity are produced which can be measured by electromyography. These subtle, typically covert, facial expression patterns differentiate depressed from nondepressed subjects. Facial electromyography can provide a sensitive, objective index of normal and clinical mood states.

Nonconscious mimicry occurs when individuals alter their mannerisms to match the behaviors and expressions of those nearby, without intention.
01:14Muscles for Facial Expressions
The craniofacial muscles are a collection of approximately 20 thin skeletal muscles situated beneath the skin of the face and scalp. These muscles, primarily responsible for the vast array of human facial expressions, originate from the bones or fibrous structures of the skull and extend outwards to connect with the skin. While most skeletal muscles in the body are enveloped in thick fascia, facial muscles generally have a more delicate fascial covering, with the buccinator muscle being a...
01:24Facial Feedback Hypothesis
Charles Darwin proposed that facial expressions are an evolutionary adaptation for communication. He argued that these expressions are not influenced by culture but are universal across species. For example, a snarling expression with exposed teeth signals a threat in many animals, including humans. Darwin also suggested that displaying an emotion can intensify the feeling. Smiling, for example, could enhance one's sense of happiness. This idea laid the foundation for understanding the role of...
