This research project is concerned with the use of mathematical techniques for processing EEG signals associated with varying states of alertness. It requires the development and implementation of advanced signal modeling and data processing techniques; especially designed for the representation and prediction of bioelectric signals useful as estimators of states of alertness. In particular, ou...

Facial mimicry (FM) is an automatic response to imitate the facial expressions of others. However, neural correlates of the phenomenon are as yet not well established. We investigated this issue using simultaneously recorded EMG and BOLD signals during perception of dynamic and static emotional facial expressions of happiness and anger. During display presentations, BOLD signals and zygomaticus...

Microbes have been able to persist in water distribution systems through the development of multicellular communities known as biofilms. This study evaluated the usefulness of the bioelectric effect for the elimination of water distribution system biofilms from annular reactors. The bioelectric effect did not have any bactericidal action either alone or when coupled with free chlorine.

A 0.5 Vrms, 12 W wirelessly powered patch type fabric sensor is presented for wearable body sensor network to continuously monitor personal bioelectric signals. Thick film electrodes are screen printed on the fabric with various metal components and their impedances of ~100k are characterized. A 2-stage nested chopped analog readout front end (AFE) is optimized for the fabric sensor with reduce...

OBJECTIVES Permanent injury to the cranial nerves can often result in a substantial reduction in quality of life. Novel and innovative interventions can help restore form and function in nerve paralysis, with bioelectric interfaces among the more promising of these approaches. The foreign body response is an important consideration for any bioelectric device as it influences the function and ef...

Traditional emotion theories stress the importance of the face in the expression of emotions but bodily expressions are becoming increasingly important as well. In these experiments we tested the hypothesis that similar physiological responses can be evoked by observing emotional face and body signals and that the reaction to angry signals is amplified in anxious individuals. We designed three ...

The majority of neurophysiological studies that have explored the role of the primate amygdala in the evaluation of social signals have relied on visual stimuli such as images of facial expressions. Vision, however, is not the only sensory modality that carries social signals. Both humans and nonhuman primates exchange emotionally meaningful social signals through touch. Indeed, social grooming...

Emotion recognition has attracted a lot of attention in recent years. It is widely used health care, teaching, human-computer interaction, and other fields. Various human emotional features are often to recognize different emotions. Currently, there more research on multimodal emotion based the fusion multiple features. This paper proposes deep learning model electroencephalogram (EEG) signals ...
