High-resolution surface electromyographic activities of facial muscles during mimic movements in healthy adults: A prospective observational study [PDF]
Frontiers in Human Neuroscience, 2022 Objectives: Surface electromyography (sEMG) is a standard tool in clinical routine and clinical or psychosocial experiments also including speech research and orthodontics to measure the activity of selected facial muscles to objectify facial movements ...

Ultrasound Imaging of the Facial Muscles and Relevance with Botulinum Toxin Injections: A Pictorial Essay and Narrative Review [PDF]
Toxins, 2022 High-resolution ultrasound is preferred as the first-line imaging modality for evaluation of superficial soft tissues, such as the facial muscles. In contrast to magnetic resonance imaging and computed tomography, which require specifically designated ...

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 ...

Keeping up appearances: Don’t frown upon the effects of botulinum toxin injections in facial muscles [PDF]
Clinical Neurophysiology Practice, 2023 Aesthetic use of low doses of Botulinum toxin (BoNT) injections into the facial muscles has become a leading non-surgical aesthetic treatment worldwide to reduce facial wrinkles, including glabellar lines, forehead lines, and periorbital wrinkles. Within

Having Difficulties Reading the Facial Expression of Older Individuals? Blame It on the Facial Muscles, Not the Wrinkles [PDF]
Front Psychol, 2021 Previous studies have found it is more difficult identifying an emotional expression displayed by an older than a younger face. It is unknown whether this is caused by age-related changes such as wrinkles and folds interfering with perception, or by the ...

Connections between the facial and trigeminal nerves: Anatomical basis for facial muscle proprioception [PDF]
JPRAS Open, 2017 Proprioception is a quality of sensibility that originates in specialized sensory organs (proprioceptors) that inform the central nervous system about static and dynamic conditions of muscles and joints.

Dynamic evaluation of facial muscles: 3D skin displacement vector analysis using a facial painting model [PDF]
Laryngoscope Investigative Otolaryngology, 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.

Human Faces Are Slower than Chimpanzee Faces [PDF]
PLoS ONE, 2014 BACKGROUND: While humans (like other primates) communicate with facial expressions, the evolution of speech added a new function to the facial muscles (facial expression muscles).

Targeted gene transfer into rat facial muscles by nanosecond pulsed laser-induced stress waves [PDF]
Journal of Biomedical Optics, 2011 We investigate the feasibility of using nanosecond pulsed laser-induced stress waves (LISWs) for gene transfer into rat facial muscles. LISWs are generated by irradiating a black natural rubber disk placed on the target tissue with nanosecond pulsed ...
