Visually evoked potentials. [PDF]

open access: possibleHandbook of Clinical Neurology, 2019
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.

Commanding a Brain-Controlled Wheelchair Using Steady-State Somatosensory Evoked Potentials

IEEE transactions on neural systems and rehabilitation engineering, 2018
In this work, we propose a novel brain-controlled wheelchair, one of the major applications of brain–machine interfaces (BMIs), that allows an individual with mobility impairments to perform daily living activities independently. Specifically, we propose

Skin denervation does not alter cortical potentials to surface concentric electrode stimulation: A comparison with laser evoked potentials and contact heat evoked potentials

European Journal of Pain, 2018
In the neurophysiological assessment of patients with neuropathic pain, laser evoked potentials (LEPs), contact heat evoked potentials (CHEPs) and the evoked potentials by the intraepidermal electrical stimulation via concentric needle electrode are ...

Evoked potentials in choreoacanthocytosis

Electroencephalography and Clinical Neurophysiology, 1986
Visual, brain-stem auditory and somatosensory evoked potentials were obtained in two patients with choreoacanthocytosis. Only minor SSEP amplitude reduction was found in one patient. Therefore evoked potentials were not helpful in identifying patients with symptoms of this disorder of up to 8 years duration.

Visual Evoked Potentials

American Journal of Electroneurodiagnostic Technology, 2008
Pattern reversal evoked potentials (PVEPs) are a noninvasive procedure that are useful for detecting lesions of the visual pathways. This article reviews anatomy of the visual pathway and the testing protocols for fullfield and hemifield PVEP and flash (goggle) visual evoked potentials (FVEP).

Evoked potentials in the ICU

European Journal of Anaesthesiology, 2008
The most informative neurophysiological techniques available in the neurosurgical intensive care unit are electroencephalograph and somatosensory evoked potentials. Such tools, which give an evaluation of cerebral function in comatose patients, support clinical evaluation and are complementary to neuroimaging.
