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 ...

Visual evoked potential estimation by eigendecomposition [PDF]

open access: yes, 1998
In this paper an eigendecomposition method is presented to estimate evoked potentials (EP). Taking into account of the characteristic of evoked potentials, the method uses two observations both of which contain desired EP signal and undesired EEG signal.

Visual Evoked Potentials as a Biomarker in Multiple Sclerosis and Associated Optic Neuritis

open access: yesJournal of neuro-ophthalmology, 2018
&NA; From the Section Editor: The next two installments in the JNO “Disease of the Year: Multiple Sclerosis” series focus on lessons that can be learned form the afferent visual pathway, as a putative model of MS.

A Comparison Study of Canonical Correlation Analysis Based Methods for Detecting Steady-State Visual Evoked Potentials

open access: yesPLoS ONE, 2015
Canonical correlation analysis (CCA) has been widely used in the detection of the steady-state visual evoked potentials (SSVEPs) in brain-computer interfaces (BCIs).

Migraine triggers and habituation of visual evoked potentials [PDF]

open access: yes, 2017
Background: Identifying specific subsets of patients within the clinical spectrum of migraine could help in personalizing migraine treatment. Profiling patients by combining clinical characteristics and neurophysiological biomarkers is largely ...

Multimodal evoked potentials and the ovarian cycle in young ovulating women [PDF]

open access: yesArquivos de Neuro-Psiquiatria, 2000
There is controversy over how hormonal conditions influence cerebral physiology. We studied pattern-shift visual evoked potentials (PS-VEP), brain stem auditory evoked potentials (BAEP) and short-latency somatosensory evoked potentials (SSEV) in 20 ...

The Fetal Visual Evoked Potential [PDF]

open access: yesPediatric Research, 1986
Five singleton fetal lambs were surgically instrumented at 110-121 days gestation (term gestation = 145 days) for measurement of visual evoked potentials (VEP) in utero. Light flashes were generated by a small incandescent bulb secured under the right fetal eyelids and the visual responses were recorded through stainless steel electrodes implanted in ...
