Influence of visual angle on pattern reversal visual evoked potentials

open access: yesOman Journal of Ophthalmology, 2014
Purpose: The aim of this study was to find whether the visual evoked potential (VEP) latencies and amplitude are altered with different visual angles in healthy adult volunteers or not and to determine the visual angle which is the optimum and most ...

Electroencephalographic brain dynamics of memory encoding in emotionally arousing context

open access: yesFrontiers in Behavioral Neuroscience, 2011
Emotional content/context enhances declarative memory through modulation of encoding and retrieval mechanisms. At encoding, neurophysiological data have consistently demonstrated the subsequent memory effect in theta and gamma oscillations.

Role of Visual Evoked Potentials in Multiple Sclerosis

open access: yesمجلة كلية الطب, 2014
Background: Multiple sclerosis (MS) is a chronic, demyelinating disease of the central nervous system (CNS) affecting young adults and is considered as the leading cause of non traumatic neurological disability of young adults affecting nearly 2 million ...

Study of visual evoked potentials in clinical practice in the patients with primary open-angle glaucoma

open access: yesJournal of Ophthalmology, 2016
Introduction. It is known that in clinical practice there are no specific neurophysiological tests for diagnosis of glaucoma; however, quite often neurophysiological examination reveals changes which are asymptomatic for a long time before the clinical ...

Cholinergic Potentiation of Restoration of Visual Function after Optic Nerve Damage in Rats

open access: yesNeural Plasticity, 2017
Enhancing cortical plasticity and brain connectivity may improve residual vision following a visual impairment. Since acetylcholine plays an important role in attention and neuronal plasticity, we explored whether potentiation of the cholinergic ...
