Biofeedback of Visual Evoked Potentials
International Journal of Neuroscience, 1986The present study investigated the operant conditioning of visual evoked potentials within a latency range between 200 and 600 ms using a visual discrimination task, and scrutinized whether biofeedback-induced potential shifts covaried with behavioral responses (reaction time, RT).

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 migraine
Neurological Sciences, 2004Migraine is a chronic disorder. Visual symptoms and hypersensitivity to light stimuli are common. The aim of this study is the analysis of visual system in migraineurs by visual evoked potentials (VEP). We studied 53 migraineurs (21 with prophylactic migraine treatment and 32 without preventive therapy) and 20 healthy control subjects.

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

Visual Evoked Potentials in Neonatal Hyperbilirubinemia
Journal of Child Neurology, 2006The management of neonatal hyperbilirubinemia is very standardized. However, there is a lack of an objective method to evaluate the cerebral effects of bilirubin apart from brainstem auditory evoked potentials. There were few studies evaluating the effects of hyperbilirubinemia or phototherapy on the visual pathway in infants with hyperbilirubinemia ...

EFFECTS OF EXERCISE ON VISUAL EVOKED POTENTIALS
International Journal of Neuroscience, 2005The aim of this study was to investigate the effects of acute or habitual exercise on visual evoked potentials (VEP). The study group consisted of 9 female and 7 male volleyball players and the control group contained 9 female and 7 male students who were not involved in any sportive activity.

Of the cortical potential evoked by visual stimuli several components can be distinguished. A very good example of VEP description was given by Ciganek (1961)/ Fig 4.1).

Transient visually evoked potential
Journal of the Optical Society of America, 1977A light delivered to the human eye will instigate changes in electrical potentials recorded over the visual cortex that last for some finite time, at least several hundred milliseconds. If the rate of stimulation is sufficiently low, the response is completed before the next visual stimulus arrives; the cortical potential is then called a transient ...

abstract Visual evoked potentials (VEPs) to repetitive flash stimuli were abnormal in 10 patients with documented hydrocephalus. Abnormalities included latency delays, fatigability, and asymmetries. Both latency and wave form disturbances improved in the postshunt period.

SummaryVEPs in neuro‐ophthalmology are important for diagnosis and surveillance of intracranial pathology. The VEP can indicate the impact of pathology along the afferent visual pathway to the striate cortex. The pathology may directly or indirectly affect the visual pathway.
