Flash visual evoked potentials in diurnal birds of prey
The objective of this pilot study was to evaluate the feasibility of Flash Visual Evoked Potentials (FVEPs) testing in birds of prey in a clinical setting and to describe the protocol and the baseline data for normal vision in this species. FVEP recordings were obtained from 6 normal adult birds of prey: n. 2 Harris's Hawks (Parabuteo unicinctus), n. 1 Lanner Falcon (Falco biarmicus), n. 2 Gyrf...
متن کاملFlash visual evoked potentials at 2-year-old infants with different birth weights.
BACKGROUND Increased prevalence of visual impairments has been reported in preterm populations. However, it remains unclear about the long-term visual electrophysiological outcomes and their association with visual cognitive functions in premature infants. We investigated visual electrophysiological outcome of 2-year-old infants of different birth weights by flash visual evoked potentials (FVEP...
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 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 کاملFlash Visual Evoked Potentials (FVEP) in Newborn Rats after Pre- and Postnatal Exposure to Zinc
The aim of this paper was to find any alterations in flash visual evoked potentials (FVeP) after preand postnatal exposure to zn in rats. 18 white adult Wistar rats drank tap water containing 50ppm of znSo4 x 7H2o and ate pelleted food during 21 days of pregnancy. 14 pregnant rats of the control group drank only tap water. 10 newborn rats from pure (without prenatal zn exposure) breeding had th...
