Clinical and electrophysiological correlation in patient with optic neuritis
Revista Cubana de Investigaciones Biomédicas, 2020 Introduction: Optic neuritis is a disorder frequently find in our environment. Material and methods: A descriptive and traverse study was performed in patients with diagnosis of optic neuritis, that attended to the neurophthalmology service of the ...

The electrophysiological assessment of visual function in Multiple Sclerosis
Clinical Neurophysiology Practice, 2019 The assessment of vision is integral to the diagnosis and monitoring of patients with multiple sclerosis (MS). Visual electrophysiology, previously a critical investigation in patients with suspected MS, has in large part been supplanted by magnetic ...

Brain Sciences, 2020 Motion-based visual evoked potentials (mVEP) is a new emerging trend in the field of steady-state visual evoked potentials (SSVEP)-based brain–computer interfaces (BCI). In this paper, we introduce different movement-based stimulus patterns (steady-state

American Journal of Neuroradiology, 2014 BACKGROUND AND PURPOSE: Functional correlates of microstructural damage of the brain affected by MS are incompletely understood. The purpose of this study was to evaluate correlations of visual-evoked potentials with microstructural brain changes as ...

A Single-Channel Consumer-Grade EEG Device for Brain-Computer Interface: Enhancing Detection of SSVEP and Its Amplitude Modulation [PDF]
IEEE Sensor Journal, 2019, 2018 Brain-Computer interfaces (BCIs) play a significant role in easing neuromuscular patients on controlling computers and prosthetics. Due to their high signal-to-noise ratio, steady-state visually evoked potentials (SSVEPs) has been widely used to build BCIs.

Journal of Neuroscience, 2013 Visual illusions and hallucinations are hallmarks of serotonergic hallucinogen-induced altered states of consciousness. Although the serotonergic hallucinogen psilocybin activates multiple serotonin (5-HT) receptors, recent evidence suggests that ...

High-performance cVEP-BCI under minimal calibration [PDF]
arXiv, 2023 The ultimate goal of brain-computer interfaces (BCIs) based on visual modulation paradigms is to achieve high-speed performance without the burden of extensive calibration. Code-modulated visual evoked potential-based BCIs (cVEP-BCIs) modulated by broadband white noise (WN) offer various advantages, including increased communication speed, expanded ...

Obtaining single stimulus evoked potentials with Wavelet Denoising [PDF]
Physica D, 2000; 145: 278-292, 2000 We present a method for the analysis of electroencephalograms (EEG). In particular, small signals due to stimulation, so called evoked potentials, have to be detected in the background EEG. This is achieved by using a denoising implementation based on the wavelet decomposition.

Steady-state visual evoked potentials and phase synchronization in migraine [PDF]
, 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 of visual stimuli.
