The Evoked Potential in Pharmacopsychiatry
Neuropsychobiology, 2008Somatosensory, visual and auditory evoked potentials (EP) were recorded in different psychiatric 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.

Auditory evoked potentials (AEPs) are an electrical manifestation of the brain response to an auditory stimulus. Mid-latency auditory evoked potentials (MLAEPs) and the coherent frequency of the AEP are the most promising for monitoring depth of anaesthesia.

Evoked potentials in trigeminal neuralgia
Neurosurgery, 1983Abstract Trigeminal evoked potentials and sensory thresholds in response to maxillary gum stimulation were obtained in patients with a complaint of unilateral face pain. The patients and the volunteer, normal control groups had undergone no prior surgical or other procedures involving cranial or cervical structures.

Loud clicks, short tone bursts, head taps and short duration transmastoid currents are all capable of activating vestibular receptors and evoking reflex changes in tonic electromyogram activity within the sternocleidomastoid muscles. Because they derive from averaged electromyograms, the responses are termed 'vestibular evoked myogenic potentials'. The

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.

SIMULTANEOUS ELECTRORETINOGRAMS AND EVOKED POTENTIALS*
Optometry and Vision Science, 1970ABSTRACT Simultancous recording of electrorctinograms and evoked cortical potentials provide the opportunity of monitoring visual activity at several functional levels. This report describes recent results obtained using the method of stimulus alternation. Bchavior of electroretinal components

Vestibular Evoked Myogenic Potentials
Current Opinion in Otolaryngology & Head & Neck Surgery, 2005Vestibular evoked myogenic potential testing is the only clinically feasible way to measure function of the saccule. Interest in this test has exploded in recent years because of its potential utility in diagnosing third-window disorders and in diagnosing and monitoring Ménière's disease.Recent literature on vestibular evoked myogenic potential covers ...

Adaptive Filterng of Evoked Potentials
IEEE Transactions on Biomedical Engineering, 1987We present an adaptive filtering (AF) technique for rapid processing of evoked potentials (EP). The AF algorithm minimizes the mean-square error (MSE) between successive ensembles. We demonstrate theoretically that the filter output converges to the least square estimate of the underlying signal.

The term visually evoked potential (VEP) refers to electrical potentials recorded from scalp overlying visual cortex that have been extracted from the electroencephalogram by signal averaging. Usually the recording electrode is placed on the midline of the occipital scalp at the back of the head.
