Bonobo facial expressions reveal complex communication; new system maps 28 moves from distinct muscle actions.

Researchers have successfully adapted a standardized system for analyzing facial expressions to include bonobos, our closest living relatives, alongside chimpanzees.

We also know that facial expressions are an important method of communication for horses. In a 2016 study, equine cognition researcher Jen Wathan and her colleagues demonstrated this when they showed ...

To do this we used something called the equine facial action coding system ().This involves two types of code: action units, which correspond to the contraction of particular facial muscles; and ...

The face contains over 40 muscles responsible for our expressions and movements. Unlike body muscles that attach to bones on both ends, many facial muscles connect directly to the skin on one end.

If the muscle attaches at a place that moves during the action of the muscle, the attachment is called an insertion. The depressor labii inferioris inserts into the skin of the lower lip.
