Data preprocessing, using principal components and Varimax rotation, was applied to 26 human average visual evoked potential (AVEP) variables representing bilateral amplitudes, latencies, and slopes from the P100 and N140 peaks. Five orthogonal factors, which accounted for about 80% of the variance, were found to describe the data from control subjects,

We investigated changes in the P100 latency of the visual evoked potential (VEP) and the saccadic reaction time (SRT) in relation to the degree of activity of the shoulder girdle elevators. Muscle force was set in 10% increments from 0% to 50% of the maximal voluntary contraction (MVC).

Abstract We investigated changes in the P100 latency of the visual evoked potential by the hemifield pattern reversal stimulation during isometric contraction of the unilateral shoulder girdle elevator. Muscle contraction force was set at 20% of maximal voluntary contraction.

To determine whether binocular summation in visual evoked cortical potential (VEP) is present in patients who have significantly different P100 peak latencies in their two eyes.Twelve patients with unilateral optic neuritis (ON) and 11 normal controls were studied.

Latency measurement improvement of P100 complex in visual evoked potentials by FMH filters
IEEE Transactions on Biomedical Engineering, 1995The ensemble average of Pattern Shift Visual Evoked Potentials (PSVEP) signals is seriously affected by random latency variations encountered in each individual sweep which is modeled as a continuous signal with linear segments and well-shaped triangular peaks. This effect is causing the smoothed peaks of the averaged PSVEP waveforms.

Comparison of latency of P100 wave in children demonstrating some pathological disorders
Acta Ophthalmologica, 2012AbstractPurpose A goal of the present paper was an assessment of usefulness of latency of P100 wave in describing few pathological disorders in children. The study group comprised 268 children, including 68 with cytomegaly (CM), 59 with myelomeningocele (MM) , 69 with purulent meningitis(PM) and 73 with Down’s syndrome (DS). The control group consisted

The aim of this study was to determine the range of normal values of the latency of the P100 component of the VEP from a control population. Weighted least squares polynomial regression analysis showed that a quadratic curve best described the relationship between age and latency and separate curves, along with normal ranges, are presented for males ...

Background & Objectives: Myopia or short-sightedness is rising globally, particularly among children and young adults with increased screen exposure. Visual evoked potentials (VEPs), measuring latencies and amplitudes, provide an objective assessment of visual pathway.
