Visual evoked potentials in monkeys
Electroencephalography and Clinical Neurophysiology, 1979Visual evoked potentials (VEPs) were recorded from 2 cortical sites in stump-tailed macaques. VEPs recorded from striate cortex were basically consistent between animals (especially at low light intensity), remained remarkably stable over time, and compared favorably to VEPs reported by other investigators.

This chapter discusses flash-induced visual evoked potentials (VEPs) and pattern-reversal visual evoked potentials (PRVEPs), their clinical utility, method of acquisition, and standard recording protocol. It describes the major components of flash VEP and PRVEP, their common morphologic variations, and influence of various subject-related and technical

The visual evoked potential (VEP) is a recording of electrical activity of the visual cortex created by stimulation of the retina. The main indications are monitoring of visual function in babies and the investigation of optic neuropathy, particularly when associated with demyelination. It can also be used to monitor macular pathway function.

One of the important goals of surgical procedures involving the visual pathways (retina, optic nerve (ON), optic chiasm, optic tracts, lateral geniculate nucleus in the thalamus, optic radiation, and occipital visual cortex) is the preservation of visual function and in cases of visual impairment, where possible, its improvement (Banoub et al ...

Visual Evoked Potentials in Alcoholics
Clinical Electroencephalography, 1983Visual evoked potentials were obtained in nineteen patients during the early phase of alcohol intoxication. Out of the thirty-eight responses recorded in the nineteen patients, 13% were found to be abnormal (5 responses). Repeated testing was done in all patients with abnormal responses at three to four week intervals following treatment with vitamins ...

Visual evoked potentials in hemiparkinsonism
Electroencephalography and Clinical Neurophysiology, 1981Abstract Visual evoked potentials (VEPs) were recorded bilaterally from the parietal areas in patients with hemiparkinsonism. VEPs recorded over the hemisphere contralateral to the side of parkinsonian symptomatology showed diminished maximal amplitude of secondary components and increased peak latency of an early positive component (P 100 ). After a

The visual evoked potential (VEP) is primarily a relatively large, positive polarity wave generated in the occipital cortex in response to visual stimulation. It measures the conduction time of neuronal activity from the retina to the occipital cortex and is used clinically as a measure of the integrity and function of that pathway.

Under the pathological conditions, the VEP may show changes in amplitude, latency, or waveform in one or more of its components. The major advantage of the pattern reversal VEP over the flash VEP lies in smaller variability in the waveform and latency of its components in the healthy population. The flash VEP is, however, particularly useful to infants
