Effect 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...

Maximally reliable spatial filtering of steady state visual evoked potentials

Due to their high signal-to-noise ratio (SNR) and robustness to artifacts, steady state visual evoked potentials (SSVEPs) are a popular technique for studying neural processing in the human visual system. SSVEPs are conventionally analyzed at individual electrodes or linear combinations of electrodes which maximize some variant of the SNR. Here we exploit the fundamental assumption of evoked re...

Efficient extraction of evoked potentials by combination of Wiener filtering and subspace methods

A novel approach is proposed in order to reduce the number of sweeps (trials) required for the efficient extraction of the brain evoked potentials (EPs). This approach is developed by combining both the Wiener filtering and the subspace methods. First, the signal subspace is estimated by applying the singularvalue decomposition (SVD) to an enhanced version of the raw data obtained by Wiener fil...

Feature 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...

Visual Evoked Potentials And Acupuncture

Visual evoked potentials (VEP) are of particular importance for the objectivization of organic and functional defects in the visual system. This study presents, for the first time, the use of systematic VEP-monitoring in connection with manual acupuncture and laserpuncture in 40 healthy volunteers. We were not able to find significant changes in latency or in the amplitudes of VEP ́s during acup...
