Atlas of voluntary facial muscle activation: Visualization of surface electromyographic activities of facial muscles during mimic exercises. [PDF]
PLoS One, 2021 Complex facial muscle movements are essential for many motoric and emotional functions. Facial muscles are unique in the musculoskeletal system as they are interwoven, so that the contraction of one muscle influences the contractility characteristic of ...

Dynamic evaluation of facial muscles: 3D skin displacement vector analysis using a facial painting model. [PDF]
Laryngoscope Investig Otolaryngol, 2021 Background Botulinum toxin A can be used to eliminate dynamic wrinkles by relaxing the muscles involved in facial expressions. Therefore, it is essential to know the location, origin, insertion, function, and changes of the facial expression muscles ...

Thermal Analysis of Facial Muscles Contractions
IEEE Transactions on Affective Computing, 2011 Facial expressions can be systematically coded using the Facial Action Coding System (FACS) that describes the specific action unit (AU) or combination of AUs elicited during different kinds of expressions. This study investigated the thermal patterns concomitant to specific action units performance.
