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

Brain, 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

Compact Convolutional Neural Networks for Classification of Asynchronous Steady-state Visual Evoked Potentials [PDF]

Journal of Neural Engineering, 2018
Steady-State Visual Evoked Potentials (SSVEPs) are neural oscillations from the parietal and occipital regions of the brain that are evoked from flickering visual stimuli. SSVEPs are robust signals measurable in the electroencephalogram (EEG) and are commonly used in brain-computer interfaces (BCIs).

A Comprehensive Review on Methodologies Employed for Visual Evoked Potentials

Scientifica, 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

Maximally reliable spatial filtering of steady state visual evoked potentials [PDF]

arXiv, 2014
Due to their high signal-to-noise ratio (SNR) and robustness to artifacts, steady state visual evoked potentials (SSVEPs) are a popular technique for studying neural processing in the human visual system. SSVEPs are conventionally analyzed at individual electrodes or linear combinations of electrodes which maximize some variant of the SNR.

Intraoperative neuromonitoring of visual evoked potentials in a pregnant patient with meningioma: a case report [PDF]

BMC Neurology
Background Meningioma in the parasellar region may lead to visual impairment, so intraoperative neurological monitoring is essential for enucleation surgery.

Assessment of visual disability using visual evoked potentials

BMC 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: Normative Values and Gender Differences [PDF]

Journal 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

Visual Evoked Potentials in Neuromyelitis Optica Spectrum Disorders [PDF]

Journal of Central Nervous System Disease, 2021
Background Neuromyelitis optica spectrum disorders (NMOSDs) are rare antibody-mediated disorders of the central nervous system, with a predilection for the spinal cord and optic nerves.

Myasthenia Gravis—An Analysis of Multimodal Evoked Potentials

Brain 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 ...
