Laser-evoked potentials: normative values.
OBJECTIVE Laser-evoked potentials (LEPs) currently represent the most reliable and widely agreed method of investigating the A delta-fibre pathways. Many studies dealt with the usefulness of LEPs in peripheral and central nervous system diseases. We aimed at gaining normative values for LEP data. METHODS Using a CO2 laser stimulator we recorded LEPs after face, hand, and foot stimulation in 1...

The Effect of Oral Verapamil on the Visual Evoked Potentials in Definite Multiple Sclerosis Patients
Introduction: Ionic channel rearrangements through the demyelinated axons or supporting media play significant role in remission of the neurological deficit in MS patients. In this study the effects of Verapamil as a calcium channel blocker on central conduction have been investigated through the evaluation of changes in P100 latency of the visual evoked potential. Method: This randomized doubl...
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...
