Assessment of Human Visual Acuity Using Visual Evoked Potential: A Review

Sensors, 2020
Visual evoked potential (VEP) has been used as an alternative method to assess visual acuity objectively, especially in non-verbal infants and adults with low intellectual abilities or malingering.

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 ...

From energy provision to protein synthesis: Tunnelling nanotubes as mediators of intercellular metabolic cooperation in cancer

FEBS Open Bio, EarlyView.
The cytoskeleton‐mediated transport of mitochondria via tunnelling nanotubes restores respiration, increases ATP production, rescues cells from apoptosis, activates the AKT/mTOR signalling pathway, promotes cell migration and invasiveness, contributes to cancer progression and treatment resistance.

Monitoring Depth of Anaesthesia Using Auditory Evoked Potential and Bispectrum [PDF]

, 2007
In this study, two methods, Auditory Evoked Potential (AEP) and bispectrum, based on EEG signal processing are employed in monitoring depth of anaesthesia. Auditory evoked potential is obtained using wavelet analysis in order to achieve a fast extraction.

A comparative study on visual evoked potential in normotensive and hypertensive individuals

National Journal of Physiology, Pharmacy and Pharmacology, 2018
Background: Hypertensive retinopathy is one of the most common complications of hypertension. Hypertension can cause changes in vascular endothelium including hyalinization, which can lead to demyelination of the optic nerve and results in conduction ...

Age-related differences in the transient and steady state responses to different visual stimuli

Frontiers in Aging Neuroscience, 2022
ObjectiveBrain-computer interface (BCI) has great potential in geriatric applications. However, most BCI studies in the literature used data from young population, and dedicated studies investigating the feasibility of BCIs among senior population are ...

The C‐terminal truncated splicing variant of NK1R negatively modulates substance P‐stimulated NK1R signaling

FEBS Open Bio, EarlyView.
The neurokinin 1 receptor exists as full‐length (NK1L) and C‐terminally truncated (NK1S) splice variants. We show that NK1S heterodimerizes with NK1L, impairing Gαq coupling and Ca2+ mobilization while enhancing β‐arrestin1 recruitment. NK1S suppresses substance P‐driven gene expression and cell migration, revealing NK1S as an endogenous biased ...

Event-related alpha suppression in response to facial motion [PDF]

, 2014
This article has been made available through the Brunel Open Access Publishing Fund.While biological motion refers to both face and body movements, little is known about the visual perception of facial motion. We therefore examined alpha wave suppression
