A Comprehensive Review on Methodologies Employed for Visual Evoked Potentials

open access: yesScientifica, 2016
Visual information is fundamental to how we appreciate our environment and interact with others. The visual evoked potential (VEP) is among those evoked potentials that are the bioelectric signals generated in the striate and extrastriate cortex when the

Recording visual evoked potentials and auditory evoked P300 at 9.4T static magnetic field. [PDF]

open access: yesPLoS ONE, 2013
Simultaneous recording of electroencephalography (EEG) and functional magnetic resonance imaging (fMRI) has shown a number of advantages that make this multimodal technique superior to fMRI alone.

Decoding Steady-State Visual Evoked Potentials From Electrocorticography [PDF]

open access: yesFrontiers in Neuroinformatics, 2018
We report on a unique electrocorticography (ECoG) experiment in which Steady-State Visual Evoked Potentials (SSVEPs) to frequency- and phase-tagged stimuli were recorded from a large subdural grid covering the entire right occipital cortex of a human ...

Visual Evoked Potentials: Normative Values and Gender Differences [PDF]

open access: yesJournal of Clinical and Diagnostic Research, 2015
Introduction: Visual evoked potentials (VEP) are used to assess the visual pathways through the optic nerves and brain. A normal VEP response to a pattern-reversal stimulus is a positive mid occipital peak that occurs at a mean latency of 100 ms. VEP

Assessment of visual disability using visual evoked potentials

open access: yesBMC Ophthalmology, 2012
Background The purpose of this study is to validate the use of visual evoked potential (VEP) to objectively quantify visual acuity in normal and amblyopic patients, and determine if it is possible to predict visual acuity in disability assessment to ...

Validating visual evoked potentials as a preclinical, quantitative biomarker for remyelination efficacy.

open access: yesBrain : a journal of neurology, 2022
Many biomarkers in clinical neuroscience lack pathological certification. This issue is potentially a significant contributor to the limited success of neuroprotective and neurorestorative therapies for human neurological disease - and is evident even in

Myasthenia Gravis—An Analysis of Multimodal Evoked Potentials

open access: yesBrain Sciences, 2021
Introduction: The aim of this study is a comprehensive analysis of the parameters of exogenous evoked potentials (visual, brainstem auditory, and somatosensory) in patients with myasthenia gravis (MG), a prototype of both neuromuscular junction disease ...

The Objective Method of the Evaluation of the Visual Acuity [PDF]

open access: yesInternational Journal of Electronics and Telecommunications, 2019
The paper presents the use of visual evoked potentials VEP to the objective assessment of visual acuity. Methods of using visual evoked potentials (VEP) rely on the assessment of changes of the electrical action potentials generated within the cortex. To

Pattern Visual Evoked Potentials and Glaucoma [PDF]

open access: yesInternational Journal Bioautomation, 2020
Aim: The aim of the study was to explore the informativity of pattern visual evoked potentials (PVEPs) as an objective method for detection of early changes in the visual analyzer (VA) function in patients with preperimetric glaucoma.

Brainstem Auditory Evoked Potentials and Visual Potentials in Kawasaki Disease: An Observational Monocentric Study

open access: yesFrontiers in Pediatrics, 2020
Background: Kawasaki Disease is a systemic vasculitis, particularly involving coronary arteries. Rare involvement of other vascular districts is described, as central nervous system arteries, leading to a vasculitic neuropathy. Sensorineural hearing loss
