This phenomenon was defined as premier expression, which Zhu and Suzuki (2016) studied in response to auditory surprise stimuli in the corrugator supercilii
muscle and zygomaticus major muscle.
The anatomy of the corrugator supercilii
muscle: part II.
The orbicularis oculi, corrugator supercilii
, platysma, mentalis, and buccinator are the most preferred muscles for injection (4).
sup], The most possible explanation is that nociceptive stimulus can increase the EMG activity of the facial muscles, especially the corrugator supercilii
muscles, which is a specific facial expression of pain.
Physical examination also revealed bilateral weakness of the facial muscles including orbicularis oris, orbicularis oculi, frontalis, and corrugator supercilii
The aims of the present study were (i) to examine the effect of exercise intensity on EMG activity of two facial muscles and to examine whether EMG activity reflects the perception of effort as well as involved muscle activity during incremental workload cycling exercise and (ii) to determine the correlations between EMG activity of corrugator supercilii
(CS) muscle (associated with frowning), that of the masseter muscle (associated with chewing), that of the vastus lateralis (VL) muscle, HR and RPE during incremental workload cycling exercise.
Also, neuromuscular monitoring of corrugator supercilii
muscle in the study could perhaps have shed additional light on timing the optimum conditions for tracheal intubation in the two study groups as current best evidence suggests that the corrugator supercilii
reflects laryngeal relaxation better than monitoring of adductor pollicis.
4) demonstrated in a cadaver study that the superficial buccal branches of the facial nerve pass around the inferior nasal margin of the orbicularis oculi muscle and cross over the medial canthal ligament to innervate the procerus, the corrugator supercilii
, and the orbicularis oculi muscles in the nasal periorbit in 94% of the specimens.
Recording at the sites of Zygomaticus major (cheek) and Corrugator Supercilii
(brow) can index positive and negative valence (Lang, Greenwald, Bradley, & Hamm, 1993; Ravaja, Saari, Turpeinen, et al.
Par ailleurs, des mesures etaient conjointement prises pour quantifier les manifestations psychophysiologiques censees varier en fonction de l'etat emotionnel du sujet: la reponse electrodermale et le taux cardiaque sont souvent lies au niveau d'activation emotionnelle; les contractions infimes des muscles corrugator supercilii
(froncement des sourcils) et zygomaticus majeur (sourire) sont liees respectivement aux reponses emotionnelles de valence negative et positive.
While perception of happy or smiling faces tends to produce a response pattern characterized by increased activity of the zygomaticus major (ZM) muscle and decreased activity of the corrugator supercilii
(CS), perception of angry faces usually leads to increased corrugator activity (e.
