Conversely, involuntary facial expressions are believed to be innate and follow a subcortical route in the brain. Facial recognition can be an emotional experience for the brain and the amygdala is highly involved in the recognition process.
Looping is where facial expressions can elicit involuntary behavior. In the research motor mimicry there shows neurons that pick up on facial expressions and communicate with motor neurons responsible for muscles in the face to display the same facial expression.

[6] Indicators of facial leakage include facial expressions that last too long, that are too intensive, or ...
Pathognomy is "a ' semiotik ' of the transient features of someone's face or body, be it voluntary or involuntary".
