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.

Amygdala Neurodegeneration: A Key Driver of Visual Dysfunction in Parkinson's Disease
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Visual disability in Parkinson's disease (PD) is not fully explained by retinal neurodegeneration. We aimed to delineate the brain substrate of visual dysfunction in PD and its association with retinal thickness. Methods Forty‐two PD patients and 29 controls underwent 3‐Tesla MRI, retinal spectral‐domain optical coherence tomography,

Transcranial magnetic stimulation-induced motor cortex activity influences visual awareness judgments [PDF]
, 2020 The influence of non-visual information on visual awareness judgments has recently gained substantial interest. Using single-pulse Transcranial Magnetic Stimulation (TMS), we investigate the potential contribution of evidence from the motor system to ...

Progressive Myoclonus Epilepsy: Distinctive MRI Changes in Cerebellar and Motor Networks
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Progressive myoclonus epilepsy (PME) is a rare generalized epilepsy syndrome with a well‐characterized genetic basis. The brain networks that are affected to give rise to the distinctive symptoms of PME are less well understood. Methods Eleven individuals with PME with a confirmed genetic diagnosis and 22 controls were studied.

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 ...

Visual Evoked Potentials and Glaucoma
Asia-Pacific Journal of Ophthalmology, 2018 Visual evoked potentials (VEP) can be used to assess the function of the visual system objectively. Research on VEP testing as a method of glaucoma evaluation has been performed for many years. Pattern VEP has shown good specificity and sensitivity in the detection of glaucoma in some studies, but other studies have not shown similar efficacy ...

FGF14 GAA Intronic Expansion in Unsolved Adult‐Onset Ataxia in the Care4Rare Canada Consortium
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Background and Objectives Spinocerebellar ataxias (SCA) represent a clinically and genetically heterogeneous group of progressive neurodegenerative diseases with prominent cerebellar atrophy. Recently, a novel pathogenic repeat expansion in intron 1 of FGF14 was identified, causing adult‐onset SCA (SCA27B). We aimed to determine the proportion

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.

Correspondence of MRI and nTMS With EDSS in Multiple Sclerosis: Longitudinal Follow‐Up Study
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objectives Considering the characteristics of multiple sclerosis (MS) disease and its impact on motor disability, this study aims to assess the functional integrity of the corticospinal tract by examining motor evoked potentials (MEPs), Expanded Disability Status Scale (EDSS) scores, magnetic resonance imaging (MRI) lesion counts, and ...
