Low-Frequency Local Field Potentials and Spikes in Primary Visual Cortex Convey Independent Visual Information [PDF]

open access: yes, 2008
Local field potentials (LFPs) reflect subthreshold integrative processes that complement spike train measures. However, little is yet known about the differences between how LFPs and spikes encode rich naturalistic sensory stimuli.

Rapid enhancement of touch from non-informative vision of the hand [PDF]

open access: yes, 2012
Processing in one sensory modality may modulate processing in another. Here we investigate how simply viewing the hand can influence the sense of touch. Previous studies showed that non-informative vision of the hand enhances tactile acuity, relative to ...

On the stimulus duty cycle in steady state visual evoked potential [PDF]

open access: yes, 2014
Brain-computer interfaces (BCI) are useful devices that allow direct control of external devices using thoughts, i.e. brain's electrical activity. There are several BCI paradigms, of which steady state visual evoked potential (SSVEP) is the most commonly

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 ...

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.

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 ...

Early Clinical and Subclinical Visual Evoked Potential and Humphrey's Visual Field Defects in Cryptococcal Meningitis. [PDF]

open access: yes, 2012
Cryptococcal induced visual loss is a devastating complication in survivors of cryptococcal meningitis (CM). Early detection is paramount in prevention and treatment.

valuation of Subclinical Multiple Sclerosis Patients Using Pattern Visual Evoked Potentials and Visual Field Test [PDF]

open access: yes, 2014
Objectives: The aim of this study was to evaluate subclinical multiple sclerosis (MS) patients with normal visual acuity using pattern visual evoked potentials (PVEP) test and central 30-2 threshold visual field (VF) test.

A Comprehensive Review on Methodologies Employed for Visual Evoked Potentials

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
