Clinical relevance of phase of steady-state VEPs to P100 latency of transient VEPs.
Electroencephalography and Clinical Neurophysiology/Evoked Potentials Section, 1991Pattern visual evoked potentials (VEPs) to transient and steady-state stimulation were recorded in 10 normal subjects at 4 levels of luminance (180, 57, 22 and 11 cd/m2). VEPs were also recorded in 5 patients with optic neuropathy at a fixed luminance (180 cd/m2).

P100 Latency as a Function of Head Size
American Journal of EEG Technology, 1991ABSTRACT.Recent studies of factors affecting the P100 latency of the pattern visual evoked potential (PVEP) have questioned the earlier assumption that gender has a statistically significant effect. Guthkelch et al. (1987) reported that head size is an important variable.

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.

The relationship of the latency of the visual P100 wave to gender and head size.
Electroencephalography and Clinical Neurophysiology/Evoked Potentials Section, 1987Six separate recordings of the pattern-reversal visual evoked potentials of 8 male and 8 female healthy adults were made. The average resulting latencies to P100 (LP100) were correlated with head length and circumference as well as with gender and latency to N70 (LN70). There was better correlation of LP100 with head circumference than with gender, and

Influence of Pupillary Size on $$\overline {{\text{P100}}}$$ Latency Time of Pattern-Reversal VEP
, 1981The relation existing between exit pupil of the eye and latency time of pattern-reversal VEP’s major positive component was evaluated. VEP recordings were performed on 5 healthy subjects. The exit pupil of the eye was varied either pharmacologically or by placing stops in front of the eye.

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).

The latencies of SEP N20, P40, N60, P100, and N140 components were measured after stimulation of two different sites, and the differences in relation to conduction velocity and their central functions are discussed. Subjects were 8 healthy right-handed males (age 22–31 years, height 164–184 cm).

BACKGROUND Fatigue in people with multiple sclerosis (PwMS) can impact physical, cognitive, and psychosocial domains of daily life. The experience of fatigue in PwMS is thought to originate from the central nervous system, particularly for the domain of ...

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
