Abstract:
The functional state of denervated muscle is a critical factor in the ability to restore movement after injury- or disease-related paralysis. Here we used peripheral optogenetic stimulation and transcriptome profiling in the mouse whisker system to investigate the time course of changes in neuromuscular function following complete unilateral facial nerve transection. While most skeletal muscles rapidly lose functionality after lower motor neuron denervation, optogenetic muscle stimulation of the paralyzed whisker pad revealed sustained increases in the sensitivity, velocity, and amplitude of w

Abstract:
Healthy humans exhibit different combinations of nonpathological, synkinetic gaze-associated movements with aural, facial, and/or masticatory muscles during different types of voluntary and reflexive horizontal eye movements. The manifestations of these collective phenomena are strongest during large-scale horizontal saccades and accompanied by a detectable horizontal chin movement. Auricular muscle activations occur equally on both sides, whereas the activation of facial and masticatory muscles is predominantly ipsilateral (in regard to gaze direction).

Abstract:
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 other mimic muscles. The facial muscles act more as a whole than as single facial muscle movements. The standard for clinical and psychosocial experiments to detect these complex interactions is surface electromyography (sEMG). What is missing, is an atlas showing which facial muscles are activated during specific tasks. Based on high-resolution

A new sensor system for measuring contraction and relaxation of muscles by using a PANDA ring resonator is proposed. The small scale optical device is designed and configured to perform the coupling effects between the changes in optical device phase shift and human facial muscle movement, which can be used to form the relationship between optical phase shift and muscle movement. By using the Optiwave and MATLAB programs, the results obtained have shown that the measurement of the contraction and relaxation of muscles can be obtained after the muscle movements, in which the unique pattern of i

This paper proposes a portable wireless transmission system for the multi-channel acquisition of surface electromyography (EMG) signals. Because EMG signals have great application value in psychotherapy and human–computer interaction, this system is designed to acquire reliable, real-time facial-muscle-movement signals. Electrodes placed on the surface of a facial-muscle source can inhibit facial-muscle movement due to weight, size, etc., and we propose to solve this problem by placing the electrodes at the periphery of the face to acquire the signals.

Human behavior is the confluence of output from voluntary and involuntary motor systems. The neural activities that mediate behavior, from individual cells to distributed networks, are in a state of constant flux. Artificial intelligence (AI) research over the past decade shows that behavior, in the form of facial muscle activity, can reveal information about fleeting voluntary and involuntary motor system activity related to emotion, pain, and deception. However, the AI algorithms often lack an explanation for their decisions, and learning meaningful representations requires large datasets la

Abstract:
This paper examines the implementation of Nitinol wire as a complex-shape actuation source specifically targeted for low-power muscle biomimetics. Nitinol is a type of shape memory alloy (SMA) which recovers its original shape after experiencing large deformation when heated above an austenite finish temperature. Previous preliminary work by the authors demonstrated successful closed-loop force control (i.e., recovery stress) using a simple proportional controller. The work presented in this paper builds upon the previous work by demonstrating closed-loop position control of various wire arran

Abstract:
Introduction: Foix-Chavany-Marie syndrome, also known as opercular syndrome, consists of voluntary orofacial muscle paralysis due to bilateral lesions in the anterior frontotemporal operculum. Classically, there is an automatic-voluntary dissociation, with impairment of speech and chewing. We present a case of a patient who had a similar presentation to opercular syndrome, secondary to unilateral ischemic lesion in the right frontal operculum. Case report: A 55-year-old, right-handed, black woman with history of arterial hypertension was admitted to the emergency department presenting left-sid

Abstract:
The word Fascia has long been used by gross anatomists to embrace a spectrum of undifferentiated mesenchymal tissues that wrap organs and tissues of the body, or form a packing material between them. The inherent implication of this traditional view is that fasciae are inconsequential residues that are less important than the tissues with which they are associated. The errors of this assumption are being exposed and undoubtedly fascia is becoming more and more of considerable importance to many professionals working in health-related disciplines. Encouragingly, there has been a strong resurgen

Abstract:
Abstract Animatronics creatively applies the skills of mechanical, electrical, and software engineering in order to recreate the movements of the creatures they replace. This paper discusses the design and development of an animatronic eye actuation and control system that reproduces realistic eye movements and expressions by drawing from the biomechanics of the human eye. Three modular, yet well integrated, eye components were developed to reproduce the movements of the eyeballs, the eyelids, and the eyebrows. The mechanical eyeballs mimic a human’s saccadic, convergence, and tracking movemen
