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 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 ...

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.

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 ...

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 ...
