<b><i>Introduction:</i></b> Eosinophilic gastroenteritis (EoG) is a rare condition with yet poorly understood pathophysiology. <b><i>Case Presentation:</i></b> We report on case of 36-year-old woman history atopy presenting nausea, abdominal discomfort, weight loss, and ascites. Laboratorial analysis revealed peripheral eosinophilia slight elevati...

The diagnosis of vitelliform macular dystrophy can be made from fundus examination alone when the classical egg-yolk lesion is intact. After the lesion has scrambled, however, other information is needed to be certain of the diagnosis. The electrooculogram (EOG) has been reported abnormal in vitelliform macular dystrophy and has been called "an indispensable diagnostic element." This paper, how...

Eye activity is one of the main sources of artefacts in EEG and MEG recordings. A new approach to the correction of these disturbances is presented using the statistical technique of independent component analysis. This technique separates components by the kurtosis of their amplitude distribution over time, thereby distinguishing between strictly periodical signals, regularly occurring signals...

Abstract To accurately identify fatigued driving, establishing a monitoring system is one of the important guarantees improving traffic safety and reducing accidents. Among many research methods, electrooculogram signal (EOG) has unique advantages. This paper presents systematic literature review these technologies summarizes basic framework fatigue driving based on EOGs. Then we summarize adva...

According to study on the group of persons with severe disabilities shows that many of them have the ability to control their eye movements, which could be used to develop various human machine interface systems to help control artifacts around them. This paper illustrates the design factor associated with the development of wireless Electro-oculography (EOG) system for paralyzed people allowin...

To improve applicability of automatic sleep staging an efficient subjectindependent method is proposed with application in sleep-wake detection and in multiclass sleep staging (awake, non-rapid eye movement (NREM) sleep and rapid eye movement (REM) sleep). In turn, NREM is further divided into three stages denoted here by N1, N2, and N3. To assess the method, polysomnographic (PSG) records of 4...

Human Machine Interface (HMI) has been extensively discussed to control electromechanical rehabilitation techniques using bio-signals such as EEG, EOG and EMG etc. When patients become completely or partially paralyzed, the only source or a resource offered to them are bio-signals. Among the various biosignals, EOG signals have been studied in depth because of the occurrence of a definite signa...

Organotypic cultures of the mouse olfactory epithelium connected to the olfactory bulb were obtained with the roller tube technique from postnatal mice aged between 13 and 66 days. To test the functionality of the cultures, we measured electroolfactograms (EOGs) at different days in vitro (DIV), up to 7 DIV, and we compared them with EOGs from identical acute preparations (0 DIV). Average ampli...

Artifacts in EEG (electroencephalogram) records are caused by various factors, like line interference, EOG (electro-oculogram) and ECG (electrocardiogram). These noise sources increase the difficulty in analyzing the EEG and to obtaining clinical information. For this reason, it is necessary to design specific filters to decrease such artifacts in EEG records. In this paper, a cascade of three ...

Odor information is first represented as a spatial activation pattern across the olfactory epithelium, when odor is drawn into the nose through breathing. This epithelial pattern likely results from both the intrinsic olfactory sensory neuron (OSN) sensitivity and the sorptive patterns imposed by the interaction of nasal aerodynamics with physiochemical properties of odorants, although the prec...
