A Comprehensive Review on Methodologies Employed for Visual Evoked Potentials

Scientifica, 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

Different visual evoked potentials in neuromyelitis optica spectrum disorder-related optic neuritis and idiopathic demyelinating optic neuritis: a prospective longitudinal analysis

BMC Ophthalmology, 2022
Background To investigate different visual evoked potential (VEP) patterns in neuromyelitis optica spectrum disorder-related optic neuritis (NMOSD-ON) and idiopathic demyelinating optic neuritis (IDON).

Selumetinib as a Target Therapy in Progressive Paediatric Low‐Grade Gliomas—Case Series (pLGG)

Journal of Paediatrics and Child Health, EarlyView.
ABSTRACT Background Optic pathway gliomas (OPGs) occur in 15%–20% of children with neurofibromatosis type 1 (NF1). While smaller gliomas may be only monitored, the current standard of care for symptomatic ones relies on chemotherapy, most commonly carboplatin and vincristine.

Visual evoked potentials in overt hypothyroid patients before and after achievement of euthyroidism

Indian Journal of Endocrinology and Metabolism, 2017
Background: Visual evoked potential (VEP) measures the time taken for visual stimulus to travel from the eye to the occipital cortex. Hypothyroidism affects the central nervous system (CNS) through its role in gene expression, myelin production, axonal ...

Reprogramming Glial Cell Metabolism via a tRNA Fragment Preserves Vision in Retinal Neurodegeneration

MedComm, Volume 7, Issue 8, August 2026.
Under oxidative and excitotoxic stress, Müller cell‐derived 5′tiRNA‐His‐GTG contributes to retinal neurodegeneration. Pathological stimuli increase ANG‐dependent production of 5′tiRNA‐His‐GTG, which suppresses LPCAT1 expression and disrupts phosphatidylcholine (PC)‐mediated glycerophospholipid metabolism.

A Hybrid Brain-Computer Interface Based on Visual Evoked Potential and Pupillary Response

Frontiers in Human Neuroscience, 2022
Brain-computer interface (BCI) based on steady-state visual evoked potential (SSVEP) has been widely studied due to the high information transfer rate (ITR), little user training, and wide subject applicability. However, there are also disadvantages such

Injectable Artificial Photoreceptors: STEM Cell Functional Integration and in vivo Electrophysiological Validation in Retinal Degeneration Models

Small Science, Volume 6, Issue 8, August 2026.
Artificial photoreceptors are engineered to efficiently absorb light, with the strongest sensitivity in the green region of the visible spectrum. Upon illumination, they generate electrical signals that activate retinal ganglion cells, which are typically unaffected by disease, enabling transmission of visual information to the brain.

Delayed evoked potentials in zebra finch (Taeniopygia guttata) under midazolam-butorphanol-isoflurane anesthesia [PDF]

PeerJ, 2019
Avian animals are visually inclined, which has caused them to attract increasing attention for visual neurophysiology or electrophysiology studies, including the study of the visual evoked potential (VEP). VEP has developed into an investigative tool for

Discovery of PHB1 as a Novel Candidate Gene in Dominant Optic Atrophy

Clinical Genetics, Volume 110, Issue 2, Page 165-171, August 2026.
A heterozygous PHB1 missense variant (p.Ser147Phe) segregates with autosomal dominant optic atrophy in a multi‐generation family. Structural and cellular analyses suggest altered mitochondrial dynamics, identifying PHB1 as a novel candidate gene for hereditary optic neuropathy. ABSTRACT Hereditary optic neuropathies comprise a genetically heterogeneous
