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...
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 کاملVisual 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...
متن کاملVisual evoked potentials in neurosyphilis.
The visual evoked potential (VEP) to pattern reversal was recorded in 79 patients with neurosyphilis. Sixteen patients (20%) had abnormal VEP latencies with a predominance of pathological VEP values in the group of tabes dorsalis (50%) as compared to general paresis (18%) or meningovascular forms (13%). A comparison of the frequency of abnormal VEPs with that of other ophthalmological tests (vi...
متن کاملVisual evoked potentials in neurobrucellosis.
OBJECTIVE To investigate whether visual evoked potentials (VEPs) are valuable for distinguishing between brucellosis with or without neurological involvement. METHODS A total of 23 patients who were admitted to the Department of Infectious Diseases and Microbiology, and Neurology, Ministry of Health Ankara Education and Research Hospital, Ankara, Turkey between December 2004 and August 2005 w...
