To be effective, signals must propagate through the environment and be detected by receivers. As a result, signal form evolves in response to both the constraints imposed by the transmission environment and receiver perceptual abilities. Little work has examined the extent to which signals may act as selective forces on receiver sensory systems to improve the efficacy of communication. If recei...

introduction: we present a retrospective two-center study series and discussion of the current literature to assess the benefits of facial nerve monitoring during parotidectomy. materials and methods: from 2007 to 2012, 128 parotidectomies were performed in 125 patients. of these, 47 procedures were performed without facial nerve monitoring (group 1) and 81 with facial nerve monitoring (group 2...

During emotion perception, context is an important source of information. Whether contextual cues from modalities other than vision or audition influence the perception of social emotional information has not been investigated. Thus, the present study aimed at testing emotion perception and regulation in response to fearful facial expressions presented in the context of chemosensory stimuli der...

EVER since Matteucci and DuBois Reymond established the fact that muscle and nerve activity is associated with bioelectric, potentials, it has been safe to assume that contraction of the heart must also have an electric correlate. Although Koelliker and Johannes Mueller actually were the first to succeed in demonstrating such electric activity, it was only when Einthoven, using a sufficiently s...

Wearable devices are used to record several physiological signals, providing unobtrusive and continuous monitoring. The main challenge in these systems is to develop new recording sensors ideally envisioning non-contact solutions. In this work we propose a wearable fiber-optic based sensor which basis of operation relies on the electro-active effect. Two main biopotential sensing components wer...

Previous studies have shown that the amygdala (AMG) plays a role in how affective signals are processed. Animal research has allowed this role to be better understood and has assigned to the basolateral amygdala (BLA) an important role in threat perception. Here we show that, when passively exposed to bodily threat signals during a facial expressions recognition task, humans with bilateral BLA ...

Emotion recognition is an attractive and essential topic in image signal processing. In this paper, we propose a multi-level fusion method to combine visual information physiological signals for emotion recognition. For information, serial of two-stage features enhance the representation facial expression video sequence. We integrate Neural Aggregation Network with Convolutional feature map rei...

The potential difference across the protoplasm of impaled cells of Halicystis is not affected by increase of oxygen tension in equilibrium with the sea water, nor with decrease down to about 1/10 its tension in the air (2 per cent O(2) in N(2)). When bubbling of 2 per cent O(2) is stopped, the P.D. drifts downward, to be restored on stirring the sea water, or rebubbling the gas. Bubbling 0.2 pe...

Patterns of resting potential in non-excitable cells of living tissue are now known to be instructive signals for pattern formation during embryogenesis, regeneration and cancer suppression. The development of molecular-level techniques for tracking ion flows and functionally manipulating the activity of ion channels and pumps has begun to reveal the mechanisms by which voltage gradients regula...
