Eye movements of participants were recorded via Biopac MP-30 system's electrooculography method.
Affected patients will have abnormal dark adaptometry and electroretinography (ERG) as well as electrooculography (EOG).
Examples of investigative activities included: (a) eye movements while reading text (measured using electrooculography, (b) visual attention and brain activity (brain-wave desynchronization measured using electroencephalography), (c) muscle-performance strength and brain control (muscle motor-unit recruitment measured using electromyography), and (d) stress and the autonomic nervous system (sympathetic and parasympathetic nervous system influence on heart-rate variability measured using electrocardiography).
This paper reports on the potential roles and importance of electrooculography (EOG) for mathematics educational neuroscience research.
Sixteen-channel PSG recordings (electroencephalography, electrooculography, electromyography of chin and leg [anterior tibialis], electrocardiography, oxygen saturation [from finger tips], respiratory effort [thoracic, abdominal] and nasal air flow, body position and tracheal microphone) were obtained for 6-8 hours with the Embla[R]-flaga instrument.
Polysomnography combines many measures to detect sleep apnea: respiratory effort, oronasal flow, pulse oximetry, electromyography (in the anterior tibial region to monitor arousal), electroencephalography or electrooculography (for sleep staging), and esophageal pressure monitoring.
A method for recording eye movement that has received some recent attention is electrooculography (EOG; see Viveash, Belyavin, Waters, & Stott, 1996).
The fEMG, EEG, and vertical electrooculography (EOG) activities were recorded using NEC 1253 Amplifiers (time constants of 0.
The Electrooculography system reflects the human eyes as electric dipoles, in view of positive pole at the cornea and its negative pole at the retina, assuming a stable Corneo-Retinal potential change, the eye is the origin of a steady electric potential field.
To detect eye motions, electrooculography (EOG) is used, which is a type of weak biomedical signal captured by electrodes attached to the skin around the eyes [6].
The system consists of 4 channels of electroencephalography, 2 channels of electrooculography, submental electromyography, oronasal airflow, thoracic and abdominal movements, pulse oximeter oxygen saturation, tibial EMG, body position detector, electrocardiogram and tracheal sound.
