Assessing the Effect of Opium Dependence on Visual Evoked Potential (VEP) in Men
Abstract Background: Opium-dependence having different effects on the nervous system is a common problem, especially in the Middle East and Iran. The aim of this study is evaluating the effects of opium-dependence on visual evoked potential (VEP) in men. Methods: Thirty subjects with both chronic cigarette smoking and opium-dependence (group 1) and 30 subjects with only chronic ciga...
متن کاملMachine learning based Visual Evoked Potential (VEP) Signals Recognition
Introduction: Visual evoked potentials contain certain diagnostic information which have proved to be of importance in the visual systems functional integrity. Due to substantial decrease of amplitude in extra macular stimulation in commonly used pattern VEPs, differentiating normal and abnormal signals can prove to be quite an obstacle. Due to developments of use of machine l...
متن کاملEffect of simulated octant visual field defects on the visual evoked potential (VEP).
everal previous clinical research studies1--6 have found he pattern visual-evoked potential (VEP) to be useful in etecting a wide range of visual-field defects objectively. n a previous study completed in our laboratory,6 circuar, annular, hemi-field, and quadrant absolute visual-field efects were simulated and assessed objectively for detecion and discrimination using the pattern VEP method. h...
متن کاملEffect of contrast on fusional visual evoked potential (VEP): a model and experimental results.
A visual evoked potential (VEP) component that appears in the power spectrum only during binocular fusion has recently been discovered. When both eyes are stimulated with the same checkerboard but at different pattern reversal rates, this fusional component appears at a frequency intermediate between the two stimulus frequencies. We have proposed a model to explain the appearance of this interm...
متن کاملAbnormalitites of Visual Evoked Potential in Migraine Patients
Background: Visual evoked potential (VEP) is regarded as a useful, reliable and non-invasive technique for the diagnosis of lesions in the optic pathway. This technique was used to investigate visual function in migraine. Materials and Methods: 53 migraine patients (27 migraine cases with aura and 26 common migraine cases) and 55 controls were prospectively enrolled in this study. Visual ev...
