Visual evoked potential from scalp in guinea pigs.

Abnormalitites 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...

Machine 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...

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...

Vestibular evoked myogenic potential : recording methods in humans and guinea pigs Summary

Vestibular evoked myogenic potential: recording methods in humans and guinea pigs.

UNLABELLED The vestibular evoked myogenic potential (VEMP) is a clinical test that assess the vestibular function by means of an inhibitory vestibulo-neck reflex, recorded in body muscles in response to high intensity acoustic stimuli. AIM To check and analyze the different methods used to record VEMPs in humans and in guinea pigs. MATERIALS AND METHODS We researched the following databases...
