To understand the connection among brain and facial muscles, we decoded correlation of muscles activities. We applied information theory (Shannon entropy) to EEG EMG signals recorded from 12 subjects (7 M, 5 F) during rest stimulation using three odors (pineapple, banana, vanilla). The results indicated that a larger variation in molecular complexity causes signals. Therefore, muscles’ activity...

BACKGROUND The trapeziometacarpal joint is subjected to high compressive forces during powerful pinch and grasp tasks due to muscle loading. In addition, muscle contraction is important for stability of the joint. The aim of the present study is to explore if different muscle activation patterns can be found between three functional tasks. METHODS Isometric forces and fine-wire electromyograp...

BACKGROUND The electrocardiogram artifact is a major contamination in the electromyogram signals when electromyogram signal is recorded from upper trunk muscles and because of that the contaminated electromyogram is not useful. Objective : Removing electrocardiogram contamination from electromyogram signals. METHODS In this paper, the clean electromyogram signal, electrocardiogram artifact an...

FeMg V O crystals grown from a MgO/Fe O /V O melt crystallize in the triclinic space group P-1 with parameters: a56.434(1) 2 3 11 2 3 2 5 ̊ ̊ ̊ A, b56.806(1) A, c510.085(1) A, a597.44(1)8, b5103.44(1)8, g5101.56(1)8 and Z52. FeZn V O crystals grown from a 2 3 11 ̊ ̊ ̊ ZnO/Fe O /V O melt also crystallize in P-1 with similar parameters: a56.455(1) A, b56.834(1) A, c59.988(1) A, a597.65(1)8, 2 3 2 5 b51...

We have calculated the equation of state and elastic properties of face-centered cubic Fe and Fe-rich FeMg alloy at ultrahigh pressures from first principles using the Exact Muffin-Tin Orbitals method. The results show that adding Mg into Fe influences strongly the equation of state, and cause a large degree of softening of the elastic constants, even at concentrations as small as 1-2 at. %. Mo...

Sensorimotor models suggest that understanding the emotional content of a face recruits a simulation process in which a viewer partially reproduces the facial expression in their own sensorimotor system. An important prediction of these models is that disrupting simulation should make emotion recognition more difficult. Here we used electroencephalogram (EEG) and facial electromyogram (EMG) to ...

The intent of this paper is to present performance evaluations for two systems that utilize electromyogram (EMG) signals from muscles in the face of the user to control the computer cursor. Both systems translate facial muscle contractions into five cursor actions: left, right, up, down and left-click. The systems perform this translation by using features derived from the spectral analysis of ...

Several models of person perception predict that expectancy violations have both affective and cognitive consequences for the perceiver. Although extant evidence generally supports these claims, the temporal resolution of traditional self-report measures has limited researchers' ability to convincingly link underlying physiological processes with observed outcomes. In this study, we examined th...

AUBADE is an integrated platform built for the affective assessment of individuals. The system performs evaluation of the emotional state by classifying vectors of features extracted from: facial Electromyogram, Respiration, Electrodermal Activity and Electrocardiogram. The AUBADE system consists of: (a) a multisensorial wearable, (b) a data acquisition and wireless communication module, (c) a ...

INTRODUCTION The important sequelae of facial nerve palsy are synkinesis, asymmetry, hypertension and contracture; all of which have psychosocial effects on patients. Synkinesis due to mal regeneration causes involuntary movements during a voluntary movement. Previous studies have advocated treatment using physiotherapy modalities alone or with exercise therapy, but no consensus exists on the o...
