IZAKI A., SHIMO-OKU M. Deparfment of Ophthalmology, Hyogo College of Medicine (Japan) Puroose : Blink reflexes evoked with comeal sensation or flash light stimulation are widely performed to examine optic, trigeminal and facial nerve. Both the electro-oculographic findings of lid movements and scleral search coil findings of eye movements during those blinks were investigated previously, we stu...
It is a known fact that brain’s neurological activity is a source of control in any brain-computer interface (BCI) system and artifacts are undesirable signals. We present a technique to reduce electrooculogram (EOG) artifacts that corrupt electroencephalogram (EEG) signals in BCI applications. The developed genetic algorithm based independent component analysis (GALME-ICA) uses mutual informat...
PURPOSE Most studies on blink-induced eye movements have been restricted to rotations about the horizontal and vertical axes. By additionally measuring rotation about the torsional axis, the authors investigated whether the three-dimensional rotation of the eye during the early phase of eyelid closure could be assigned to the action of a single extraocular muscle. METHODS In five healthy huma...
Eye movements, eye blinks, cardiac signals, muscle noise, and line noise present serious problems for electroencephalographic ~EEG! interpretation and analysis when rejecting contaminated EEG segments results in an unacceptable data loss. Many methods have been proposed to remove artifacts from EEG recordings, especially those arising from eye movements and blinks. Often regression in the time ...
Electroencephalography (EEG) measures the electrical brain activity in real-time by using sensors placed on scalp. Artifacts, due to eye movements and blink, muscular/cardiac generic disturbances, have be recognized eliminated allow a correct interpretation of useful signals (UBS) EEG. Independent Component Analysis (ICA) is effective split signal into independent components (ICs) whose re-proj...
Objective: Recent advances in development of low-cost single-channel electroencephalography (EEG) headbands have opened new possibilities for applications health monitoring and brain-computer interface (BCI) systems. These recorded EEG signals, however, are often contaminated by eye blink artifacts that can yield the fallacious interpretation brain activity. This paper proposes an efficient alg...
We examined the hypothesis that rejection automatically elicits defensive physiological reactions in people with low self-esteem (SE) but that attentional control moderates this effect. Undergraduates (N= 67) completed questionnaire measures of SE and attentional control. Their eye-blink responses to startle probes were measured while they viewed paintings related to rejection and acceptance th...
