Optimal Detection of Multiharmonic Visually Evoked Potentials
We consider the problem of detecting visual evoked potentials (VEP's). A matched subspace lter is applied to the detection of the VEP and is demonstrated to perform better than a number of other evoked potential (EP) detectors. Unlike single-harmonic detectors, the MSF detector is suitable for detecting multi-harmonic VEP's. Moreover, the MSF is optimal in the uniformly most powerful (UMP) sens...
متن کاملDetection of Artifacts in Visual Evoked Potentials
The aim of this work is to introduce correlation test to detect artifacts in visual evoked potentials. If an artifact occurs a sample signal deviates from the ensemble average. In this paper signals with less correlation coefficient are considered as artifacts and are removed from the further analysis. An attempt has been made to apply these techniques to 14 -channel visual evoked potentials (V...
متن کاملFeature Extraction of Visual Evoked Potentials Using Wavelet Transform and Singular Value Decomposition
Introduction: Brain visual evoked potential (VEP) signals are commonly known to be accompanied by high levels of background noise typically from the spontaneous background brain activity of electroencephalography (EEG) signals. Material and Methods: A model based on dyadic filter bank, discrete wavelet transform (DWT), and singular value decomposition (SVD) was developed to analyze the raw data...
متن کاملLow-luminance contrast stimulation is optimal for early detection of glaucoma using multifocal visual evoked potentials.
PURPOSE The blue-on-yellow multifocal visual evoked potential (BonY mfVEP) stimulus is more sensitive than the conventional black-and-white pattern-reversal stimulus in identifying early glaucoma. BonY employs pattern-onset stimulation and lower luminance contrast (40%) in addition to color. This study was conducted to elucidate the mechanism responsible for the enhanced performance of the BonY...
متن کاملPossible Long Term Effects of Chemical Warfare Using Visual Evoked Potentials
Some studies have already addressed the effects of occupational organic solvent exposure on the visually evoked potentials (VEPs). Visual system is an important target for Sulphur Mustard (SM) toxicity. A number of Iranian victims of Sulphur Mustard (SM) agent were apprehensive about the delay effect of SM on their vision and a possible delay effect of SM on their visual cortex. This investigat...
