Current views on face perception assume that the visual system receives only visual facial signals. However, I show that the visual perception of faces is systematically biased by adaptation to a haptically explored face. Recently, face aftereffects (FAEs; the altered perception of faces after adaptation to a face) have been demonstrated not only in visual perception but also in haptic percepti...

Gaze direction signals another person's focus of interest. Facial expressions convey information about their mental state. Appropriate responses to these signals should reflect their combined influence, yet current evidence suggests that gaze-cueing effects for objects near an observed face are not modulated by its emotional expression. Here, we extend the investigation of perceived gaze direct...

The paper aimed to explore the ability of bioelectric technology combined with acupoint stimulation on collagen concentration and prognosis invalid. Between June 2020 2021, study recruited 400 patients who underwent stress urinary incontinence in urology reconstructive pelvic surgery. They were divided into experimental group (bioelectric stimulation, n=200) control (simple according odd-even m...

Externally powered prostheses have been studied for many years, in efforts to provide more effective rehabilitation of amputees. In order to take advantage of the benefits offered by external poser in prostheses, however, the mode of control of the prosthesis by tWe amputee must also be improved. Conventional control methods require a high degree of mental concentration by the amputee on his pr...

The amygdala is critically involved in mediating physiological and behavioral responses to threat. In particular, neuroimaging research indicates that the amygdala is highly responsive to facial signals of threat such as fearful and angry expressions. However, individuals differ substantially in both their relative sensitivity to threat and the magnitude of amygdala reactivity to facial signals...

Changes in the human face occur due to many factors, including communication, emotion, speech, and physiology. Most systems for facial expression analysis attempt to recognize one or more of these factors, resulting in a machine whose inputs are video sequences or static images, and whose outputs are, for example, basic emotion categories. Our approach is fundamentally different. We make no pri...

In recorded bioelectric signals, such as the electrocardiogram, sinusoidal interference from power lines or other sources causes distortion in the signal and may lead to misdiagnosis. For long or continuous recordings, adaptive filtering can be effective in minimizing the interference. For short recording, the options are limited. Subtractive methods have been used, but they do not distinguish ...

This overview provides the basic information needed to understand, choose, and use fluorescent bioelectricity reporters (FBRs), where bioelectricity is defined as cell processes that involve ions or ion flux. While traditional methods of measuring these characteristics are still valid and necessary, the utility of FBRs has facilitated measurement of these properties under circumstances that are...

Every second, in an average daytime light environment, hundreds of millions of photons enter the human eye and arrive at the photoreceptor layer of the retina. All our information about the visible world is contained in this rain of photons. The retina is a complex tissue, literally an extension of the brain, which transforms the rain of photons into bioelectric signals containing all the infor...
