The recording of visual evoked potentials (VEPs) is an important means of obtaining reproducible, quantitative data on the function of the anterior visual pathways. In this review, the technical aspects of recording VEPs are briefly discussed, components of the VEPs are described, and the clinical uses of VEPs are considered.

Evoked Potentials in the Elderly
Journal of Clinical Neurophysiology, 1995Evoked potentials (EPs) provide a quantitative measure of function rather than structure of certain pathways and processes within the nervous system. These systems and processes change with maturation and senescence. There are minimal somatosensory EPs changes after maturation until senescence. There are moderate changes in interpeak latencies, but few

Reaction time (RT) differences to visual stimuli as a function of expectancy have been attributed to changes in perceptual processing or entirely to shifts in decision and response criteria.

Evoked potentials and psychopathy
International Journal of Psychophysiology, 1989All previous studies which have assessed evoked potentials (EPs) in psychopathic populations are critically reviewed. Three main themes emerge from this review. Firstly early EP studies suggest a dysfunctional arousal system at a brainstem or parietal cortex level in psychopaths.

Brain-Computer Interfaces Based on Visual Evoked Potentials
IEEE Engineering in Medicine and Biology Magazine, 2008Recently, electroencephalogram (EEG)-based brain- computer interfaces (BCIs) have become a hot spot in the study of neural engineering, rehabilitation, and brain science.

Visual evoked potentials (VEPs) have a role in evaluating patients with neurologic disease affecting the optic pathway. In patients with lesions involving the optic nerve and anterior chiasm, VEPs have several important advantages: (1) they are objective and reproducible and may demonstrate a functional abnormality that is not evident on physical ...

Electrically evoked nociceptive potentials for early detection of diabetic small‐fiber neuropathy
European Journal of Neurology, 2010Background and purpose: This study investigated the utility of pain‐related evoked potentials (PREP’s) elicited by a nociceptive electrical stimulation of the skin (= electrically evoked nociceptive potentials) in early detection of diabetic small‐fiber

Auditory evoked potentials (AEPs) have become an integral part of the current otologic/audiologic test battery. With these techniques, synchronous neural activity can be examined from the peripheral end organ of hearing up to the cortical structures responsible for audition.

The Evoked Potential in Pharmacopsychiatry
Neuropsychobiology, 1977Somatosensory, visual and auditory evoked potentials (EP) were recorded in different psychatric populations before as well as during psychotropic drug treatment. Drug-free schizophrenic patients showed shorter latencies, smaller amplitudes and an increased intraindividual variability in their EP than controls.
