Frequency Domain Analyses of Neonatal Flash VEP
The flash visual evoked potential (VEP) has been widely used during infancy for tracking developmental changes in visual maturation and assessing...

Het VEP of visueel geëvokeerde potentialen meet de werking van de visuele banen vanaf het oog tot in de hersenen. U kijkt naar lichtflitsen (flits-VEP) of naar een beeldscherm (patroon-VEP). Het EOG of elektro-oculogram meet de werking van het retinaal pigmentepitheel.
临床视觉诱发电位标准 - 中华眼科杂志
视觉诱发电位（visual evoked potential，VEP）是指视网膜受到视觉刺激后在大脑枕叶视皮层诱发的电位活动。 视皮层电位活动主要由中央视野激活。 VEP依赖整个视觉通路的功能完整性，包括眼球、视网膜、视神经、视放射和枕叶视皮层。 本文更新了国际临床视觉电生理学会（International Society for Clinical Electrophysiology of Vision，ISCEV）临床VEP检测标准，并取代了2009年的临床VEP标准 [ 1 ]。 与之前的标准相比，本标准的主要变化：（1）认可各种可 …

Jan 1, 2023 · The visual evoked potential (VEP) is a means of extracting from the spontaneous electrical activity in the brain, electrical changes that are directly related to a specific brain action. It is a means of analyzing the Electroencephalogram (EEG). The event-related information (“signal”) is extracted from the overall electrical activity ...
Electrodiagnostic tests of the visual pathway and applications in …
Jun 11, 2024 · The pattern appearance-disappearance VEP (PA-VEP), also referred to as onset-offset VEP, is a response to a checkerboard that alternates with a diffuse background...
Visual Evoked Potentials - SpringerLink
The visual evoked potential (VEP) is primarily a relatively large, positive polarity wave generated in the occipital cortex in response to visual stimulation. It measures the conduction time of neuronal activity from the retina to the occipital cortex and is used clinically as a measure of the integrity and function of that pathway.
Frequency-dependent dynamics of steady-state visual evoked
Apr 23, 2024 · Steady-state visual evoked potentials (SSVEP) are electroencephalographic signals elicited when the brain is exposed to a visual stimulus with a steady frequency. We analyzed...
Visually Evoked Potentials - Webvision - NCBI Bookshelf
Mar 1, 2012 · The terms visually evoked potential (VEP), visually evoked response (VER) and visually evoked cortical potential (VECP) are equivalent. They refer to electrical potentials, initiated by brief visual stimuli, which are recorded from the scalp overlying visual cortex.
Dit leidt in het ‘visual evoked potential’ (VEP)-onderzoek bij ‘pattern-onset’ of flitsstimulatie van één oog tot een asymmetrische respons over beide hemisferen, waarvan de polariteit omkeert bij stimulatie van het andere oog. De VEP-asymmetrie wordt in dit artikel nader toegelicht en geïllustreerd aan de hand van een casus.
