Weakness or paralysis of the facial muscles is one of the most common features of Moebius syndrome. (medlineplus.gov)
Abnormal development of cranial nerves leads to the facial muscle weakness or paralysis that is characteristic of Moebius syndrome. (medlineplus.gov)
An inability to move the muscles of the face on one or both sides is known as facial paralysis. (hopkinsmedicine.org)
Facial paralysis can result from nerve damage due to congenital (present at birth) conditions, trauma or disease, such as stroke , brain tumor or Bell's palsy . (hopkinsmedicine.org)
The facial plastic surgery team determines the best treatment based on how long the paralysis has been present, the cause and whether it is a complete paralysis, or an incomplete (or partial) paralysis. (hopkinsmedicine.org)
Facial paralysis surgery is also called facial reanimation surgery. (hopkinsmedicine.org)
Because of the importance of facial mobility in creating recognizable facial expressions and communicating with others, addressing paralysis of the face is more than a cosmetic concern, especially in children. (hopkinsmedicine.org)
Bell palsy is an unexplained episode of facial muscle weakness or paralysis. (uhhospitals.org)
During Mary Jo's first appearance, she said she continued to suffer from facial paralysis and ear damage from the shooting. (oprah.com)
Muscle weakness - Paralysis can occasionally spread and affect chewing or facial expressions. (cdhp.org)
Their observational cohort study of patients with migraine and matched controls found that the association between migraine and Bell's palsy, an acute, ipsilateral facial nerve paralysis that results in weakness of the platysma and muscles of facial expression, was not affected by sex or migraine subtype. (medscape.com)
If untreated, illness from any type of botulism can progress to descending paralysis of respiratory muscles, arms, and legs. (cdc.gov)

The macaque provides a model visual system for studying neural coding of expression movements, as its superior temporal sulcus (STS) possesses brain areas selective for faces and areas sensitive to visual motion. (jneurosci.org)
However, their visual systems must cope with a difficult computational challenge: they must extract information about facial expressions despite complex naturalistic movements. (jneurosci.org)
In the macaque, electrophysiological and functional magnetic resonance imaging (fMRI) studies have localized candidate areas that could encode facial movements. (jneurosci.org)
or facial movements. (jneurosci.org)

Facial expressions and muscle movements control playback, so smiles, winks, and twitches determine the beats you hear. (makezine.com)
Dynamic expression lines are the wrinkles that take place due to the movements of facial muscles. (greenopolis.com)
Some of the muscle movements described by Dr. Ekman are so subtle that only a trained expert can detect movement. (informit.com)
However, most of these facial muscle movements and especially the subtle ones can actually be observed and felt by the amygdala of people even if these people did not consciously perceive the movement. (informit.com)
An algorithm then assesses each individual's facial muscle movements and biometric signals. (trak.in)
Observe facial and leg movements. (medscape.com)
Although researchers have investigated how facial muscle movements, in the form of facial expressions, correlate with social impressions, few studies have specifically examined how head movements might play a role. (psychologicalscience.org)
People often display certain movements or expressions during their everyday interactions, such as a friendly smile or wave, as a way to communicate information. (psychologicalscience.org)
Our research suggests that we may also want to consider how we hold their head during these interactions, as subtle head movements can dramatically change the meaning of otherwise innocuous facial expressions. (psychologicalscience.org)

While created to study human expression, Dr. Ekman's Facial Action Coding System (FACS) has served an important role in the study of animal emotions and facial expressions. (paulekman.com)
While the various animal FACS systems do not make direct inferences about underlying emotions, the observable objective measurements made possible by these systems provide promising platforms for future research further investigating the relationship between animal facial expressions and emotion. (paulekman.com)
This profound link sheds light on how our internal well-being and emotions can be reflected in our facial features. (kevinmd.com)
In the 1990s, Dr. Ekman proposed a list of these basic emotions, including a range of positive and negative emotions that are not all encoded in facial muscles. (informit.com)
Designed by the Chinese tech firm Taigusys, this system would monitor employees' emotions by tracking their facial expressions in the workplace. (trak.in)
Hence, in addition to the support of the evolutionary hypothesis of the female superiority in detecting facial expressions of emotions, recognition of facial expressions also depend on the time available to correctly identify an expression. (bvsalud.org)
The correct identification of facial emotions plays a fundamental role in the evolution of the social species, of which we belong. (bvsalud.org)

Several mechanisms may explain the link between migraine and Bell's palsy, but the "top hypothesis," according to Dr Wang, is that neurogenic inflammation of nearby cranial nerves may predispose the facial nerve to demyelination, perhaps after a viral infection. (medscape.com)

We used functional magnetic resonance imaging and facial stimuli to localize motion-sensitive areas [motion in faces (Mf) areas], which responded more to dynamic faces compared with static faces, and face-selective areas, which responded selectively to faces compared with objects and places. (jneurosci.org)
We also show that some of the motion sensitivity elicited by facial stimuli was not specific to faces but could also be elicited by moving dots, particularly in fundus of the superior temporal and middle superior temporal polysensory/lower superior temporal areas, confirming their already well established low-level motion sensitivity. (jneurosci.org)
This area has not been previously reported using low-level motion stimuli and it is unknown whether it is also sensitive to facial motion or whether it encodes facial expressions. (jneurosci.org)
