Superposition Model Predicts EEG Occipital Activity during Free Viewing of Natural Scenes
(2010-03-31)
Visual event-related potentials (ERPs) produced by a stimulus are thought to reflect either an increase of synchronized activity or a phase
realignment of ongoing oscillatory activity, with both mechanisms sharing the ...
Optimizing outcomes in multiple sclerosis: Consensus guidelines for the diagnosis and treatment of multiple sclerosis in Latin America
(SAGE Publications, 2011)
Objective: The prevalence of multiple sclerosis (MS) in Latin America varies across different studies but an intermediate risk and increased frequency of the disease have been reported in recent years. The circumstances ...
SoC-FPGA systems for the acquisition and processing of electroencephalographic signals
(Institute of Advanced Engineering and Science, 2021-11-03)
Real-time acquisition and processing of electroencephalographic signals have promising applications in the implementation of brain-computer interfaces. These devices allow the user to control a device without performing ...
Prenatal malnutrition-induced functional alterations in callosal connections and in interhemispheric asymmetry in rats are prevented by reduction of noradrenaline synthesis during gestation
(1998)
Prenatal malnutrition results in increased concentration and release of central noradrenaline, a neurotransmitter that is an important regulator of normal regressive events such as axonal pruning and synaptic elimination. ...
Coding model of visual stimuli in the optic nerve
(Institute of Electrical and Electronics Engineers, 2018-08-27)
Electrophysiological records are a standard procedure in the study of neuronal coding in the visual system. In this paper we propose a model that can predict the electrophysiological record of electrical activity in the ...
Modulação centro-contorno em campos receptivos do wulst visual
(Universidade Federal de Minas GeraisUFMG, 2011-10-07)
Neurons in the primary visual cortex (V1) typically show responsesuppression when stimulated by oriented stimuli larger than their classical receptive fields (CRF). Here, we investigate the prevalence, strength and feature ...
Estudo do potencial evocado visual em regime permanente baseado em LED para interface cérebro máquina
(Universidade Federal de Minas GeraisUFMG, 2011-11-30)
The Steady State Visual Evoked Potential (SSVEP) is the brains electrical response to intermittent visual stimulation. This has applications in medical clinic and in studies of the neurophysiology of vision and more recently ...
A cholinergic gating mechanism controlled by competitive interactions in the optic tectum of the pigeon
(2007)
We describe the operation of a midbrain neural circuit in pigeons that may participate in selecting and attending to one visual stimulus from the myriad displayed in their visual environment. This mechanism is based on a ...

Alterações encontradas no potencial visual evocado por padrão reverso em pacientes com esclerose múltipla definida
(Conselho Brasileiro de Oftalmologia, 2007-12-01)
INTRODUCTION: Multiple sclerosis is an idiopathic demyelinating disease that may affect the optic nerve leading to acute unilateral visual loss, which could be observed by means of evoked visual potential (VEP). This exam ...
