Emotion produces complex neural processes and physiological changes under appropriate event stimulation. Physiological signals have the advantage of better reflecting a person’s actual emotional state than facial expressions or voice signals. An electroencephalogram (EEG) is signal obtained by collecting, amplifying, recording human brain’s weak bioelectric on scalp. The eye-tracking (E.T.) rec...

This paper introduces a method to remove the unwanted interdependency between vertical and horizontal eye-movement components in electrooculograms (EOGs). EOGs have been widely used to estimate eye movements without a camera in a variety of human-computer interaction (HCI) applications using pairs of electrodes generally attached either above and below the eye (vertical EOG) or to the left and ...

AIM To explore the effects of omeprazole on chemoradiotherapy efficacy and tumor recurrence in rectal cancer. METHODS The medical data of 125 rectal cancer patients who received the same neoadjuvant chemoradiotherapy (CRT) followed by surgery were retrospectively collected. Patients who received omeprazole (OME) orally at a dose of 20 mg at least once daily for six days and/or intravenously a...

For anadromous salmonids, olfaction is a critical sense, enabling return migration. In recent years, several pesticides have been identified that interfere with salmonid olfaction at concentrations in the microg/L range; thus, they may pose a risk to species longevity. In the present study, we investigated the acute effects of five agricultural pesticides on juvenile coho salmon (Oncorhynchus k...

Clinical electrooculography requires a patient to track two points in the visual field separated by at least 30” visual angle in a horizontal plane while recording the concomitant change in potential from electrodes placed at the external canthi of the two eyes. This test is relatively lengthy, requiring long periods of light and dark adaptation. A minicomputer program has been written to autom...

Psychological status monitoring with cerebral blood flow (CBF), EEG and EOG measurements are attempted. Through experiments, it is confirmed that the proposed method for psychological status monitoring is valid. It is also found correlations among the amplitudes of peak alpha and beta as well as gamma frequency of EEG signals and EOG as well as cerebral blood flow. Therefore, psychological stat...

this study investigates the detection of the drowsiness state for a future application such as in the reduction ofthe road traffic accidents. the electroencephalography(eeg), electrooculography (eog), driving quality (dq), and karolinska sleepiness scale (kss) data of 7 male during approximately 20 hours of sleep deprivation were recorded. to reduce the eye blink artifact, an automatic mechanis...

A method based on regression analysis is presented that can be used for automatic minimization of EOG and ECG artifacts in the sleep EEG. INTRODUCTION It is known that the non-cortical activity gives a contribution to the EEG recordings. Electrooculogram (EOG), the electrocardiagram (ECG) and muscle activity (EMG) are the most important non-cortical sources. For sleep analysis it is important t...

Eyes are the windows to the brain and the eye movements are a rich source of information in information processing. The aim of this paper is to select the features with CBFS Feature selection algorithm using eye movements by ElectroOculoGraph (EOG) signals during reading and writing task. The objective is to impart the fundamental functionality to get an extensive understanding of how EOG signa...

To provide an efficient means of communication for those who cannot move muscles of the whole body except eyes due to amyotrophic lateral sclerosis (ALS), we are developing a speech synthesis interface that is based on electrooculogram (EOG) input. EOG is an electrical signal that is observed through electrodes attached on the skin around eyes and reflects eye position. A key component of the s...
