Comparison of the effect of sedation and general anesthesia on pattern and flash visual evoked potentials in normal dogs [PDF]

open access: yesBMC Veterinary Research, 2022
Background Visual evoked potentials (VEPs) can provide objective functional assessment of the post-retinal visual pathway. This study compared the effects of sedation (butorphanol and dexmedetomidine) and general anesthesia (propofol and sevoflurane) on ...

Variability, repeatability and test-retest reliability of equine flash visual evoked potentials (FVEPs) [PDF]

open access: yesBMC Veterinary Research, 2020
Background Visual evoked potentials (VEPs) are electrical potentials generated by neurons in the central nervous system in response to visual stimuli. A series of positive and negative wavelets in response to flash-stimuli (flash-VEP; FVEP) or reversing,

Flash visual evoked potentials in diurnal birds of prey [PDF]

open access: yesPeerJ, 2016
The objective of this pilot study was to evaluate the feasibility of Flash Visual Evoked Potentials (FVEPs) testing in birds of prey in a clinical setting and to describe the protocol and the baseline data for normal vision in this species.

Differential deficits in pattern- versus flash-visual evoked potentials in schizophrenia: relationship to subcortical visual systems, pulvinar nucleus and cognition [PDF]

open access: yesFrontiers in Neuroimaging
BackgroundThe human subcortical visual system is divided into distinct magnocellular, parvocellular and koniocellular pathways, which contribute differentially to specific aspects of early visual processing.

Flash visual evoked potentials in patients with periventricular leucomalacia in children less than 1 year of age

open access: yesIndian Journal of Ophthalmology, 2013
Background and Aim: Children with periventricular leucomalacia (PVL) are known to have visual impairment of various forms starting from reduced vision, field defects, congnitive problems, and problems with hand eye coordination.

Resting state in Alzheimer's disease: a concurrent analysis of Flash-Visual Evoked Potentials and quantitative EEG [PDF]

open access: yesBMC Neurology, 2012
Background To investigate to what extent Alzheimer's Disease (AD) affects Resting State activity, the possible impairment of independent electrophysiological parameters was determined in Eye-open and Eye-closed Conditions.

Layers of the monkey visual cortex are selectively modulated during electrical stimulation. [PDF]

open access: yesPLoS Biology
The mammalian neocortex, organized into six cellular layers or laminae, forms a cortical network within layers. Layer-specific computations are crucial for sensory processing of visual stimuli within the primary visual cortex. Laminar recordings of local

Environmental Enrichment Enhances Visual Function in Adult Amblyopia: Association With miR-132/HDAC3 Regulation [PDF]

open access: yesNeural Plasticity
Amblyopia is a neurodevelopmental disorder for which effective treatments in adults are limited due to reduced cortical plasticity. Environmental enrichment (EE) can partially restore this plasticity, but the underlying molecular mechanisms remain ...

The Diagnostic Value of Visual Evoked Potentials in Chronic Disorders of Consciousness [PDF]

open access: yesAnnals of Clinical and Translational Neurology
Objective In chronic disorders of consciousness (DOCs), the distinction between vegetative state/unresponsive wakefulness syndrome (VS/UWS) and minimally conscious state (MCS) is as crucial as it is challenging.

Efficiency of the treatment of epilepsy in adolescent children according to indicators of evoked potentials

open access: yesJournal of Education, Health and Sport, 2023
The aim: to identify the peculiarities of the indicators of evoked potentials in epileptic children against the background of anticonvulsant treatment. Methods: auditory long-latency, visual flash-evoked potentials.  Epileptic children were divided into
