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

Visual evoked potentials in the horse [PDF]

open access: yesBMC Veterinary Research, 2016
Electrical potentials generated in the central nervous system in response to brief visual stimuli, flash visual evoked potentials (FVEPs), can be recorded non-invasively over the occipital cortex. FVEPs are used clinically in human medicine and also experimentally in a number of animal species, but the method has not yet been evaluated in the horse ...

Efficiency of the treatment of epilepsy in adolescent children according to indicators of evoked potentials [PDF]

open access: yesJournal of Education, Health and Sport, 2023
The aim: to identify the peculiarities of the indicators of evoked potentials in epileptic children against the background of anticonvulsant treatment. Methods: auditory long-latency, visual flash-evoked potentials.  Epileptic children were divided into

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.

Steady-state visual evoked potentials and phase synchronization in migraine [PDF]

open access: yes, 2004
We investigate phase synchronization in EEG recordings from migraine patients. We use the analytic signal technique, based on the Hilbert transform, and find that migraine brains are characterized by enhanced alpha band phase synchronization in presence of visual stimuli.

Visual Evoked Potentials in Phenylketonuria

open access: yesPediatric Neurology Briefs, 1995
Visual evoked potentials (VEPs) were studied in 36 patients with phenylketonuria, and compared with MRI findings, dietary state, and IQ at the Institute of Neurology, Queen Square, and the Institute of Child Health, Great Ormond Street Hospital, London ...

A Comprehensive Review on Methodologies Employed for Visual Evoked Potentials [PDF]

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

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 ...

Assessment of visual disability using visual evoked potentials [PDF]

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 ...

Visual Evoked Potentials in Rett Syndrome

open access: yesPediatric Neurology Briefs, 2015
Investigators from the Boston Children's Hospital recorded pattern-reversal visual evoked potentials (VEPs) in Mecp2 heterozygous female mice and in 34 girls with Rett syndrome (RTT).
