[A dual process model for on and off visual evoked potentials].
A model of consisting of excitatory and inhibitory processes was proposed for visual evoked potentials (VEPs) from the midline occiput (Oz). On and off stimulation of circular lights subtending 2 degrees and 5 degrees in visual angle were presented with luminance contrast of 1.0, 2.2, and 3.4. The typical triphasic data from a well trained male subject were analysed and decomposed into the two ...
متن کاملEffect of blue-light filtering on multifocal visual-evoked potentials.
PURPOSE To perform an objective functional assessment of the impact of blue-light filters on cortical processing to evaluate the potential side effects of the filters on higher tier visual function at the neural level. SETTING Department of Ophthalmology, Otto-von-Guericke-University Magdeburg, Magdeburg, Germany. DESIGN Cohort study. METHODS Multifocal pattern-reversal visual-evoked pote...
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 کاملStandard for Visual Evoked Potentials 1995
A revised ISCEV standard for clinical electro-retinography has been published (1995). It is our concern that similar standards should be adopted for visual evoked potentials (VEP). The VEP is an electrophysiological signal that is recorded at the scalp, using standard EEG techniques. When used with other visual electrophysiological techniques the VEP can provide important diagnostic information...
متن کاملNoradrenergic modulation of human visual cortex excitability assessed by paired-pulse visual-evoked potentials.
Paired-pulse paradigms are common tools to explore excitability in the human cortex. Although the underlying mechanisms of intracortical inhibition and facilitation in the motor system assessed by paired transcranial magnetic stimulation are well understood, little is known about the physiology of excitability in the human cortex measured by paired-pulse visual-evoked potentials (VEPs). We ther...
