Somatosensory Evoked Potentials

2009
SEPs recorded with surface electrodes represent volume-conducted activity arising from myelinated peripheral and central axons, synapses in central gray matter, and changes in the size and shape of the volume conductor. They provide an objective measure of function in large-diameter myelinated sensory afferents peripherally and in proprioceptive ...

Somatosensory Evoked Potentials

2020
This chapter discusses somatosensory evoked potentials (SSEPs) elicited by stimulation of large mixed nerves in the upper and lower extremities, their clinical utility, method of acquisition, and standard recording protocol. This chapter describes the major components of median and posterior tibial SSEPS, and their generator sources, emphasizing near ...

Somatosensory Evoked Potentials

1983
Somato sensory evoked potentials are potentials which are elicited by means of stimuli on the skin, sensory organs or the sensory nerves. They are derived from the peripheral nerves or the central nervous system.

Somatosensory evoked potentials in abetalipoproteinemia

Electroencephalography and Clinical Neurophysiology, 1985
Visual, brain-stem auditory, and somatosensory evoked potentials (SEPs) were obtained on a patient with known abetalipoproteinemia. Only the SEP was abnormal, and it correlated with the reported neuropathology of this disease. Serial SEP studies remained stable, as had the clinical condition of this patient on vitamin E therapy.

Long latency somatosensory evoked potentials

Journal of Clinical Neurophysiology, 1986
Theoretically, long-latency somatosensory evoked potentials (SEPs) provide information on the function of somatosensory associative cortical structures. Their potential role in clinical studies and research has been hampered by the lack of standardized methodology in the use of these SEPs.

Intraspinal Localization of the Somatosensory Evoked Potential

Neurosurgery, 1981
Abstract Somatosensory evoked potentials (SEPs) are used widely for monitoring neurophysiological function in experimental spinal injury. Yet the spinal pathways for SEP conduction remain unclear. Consequently, we sought to define specific changes in the SEP after interruption of selected spinal pathways.

Somatosensory-Evoked Potentials in the Ventrolateral Thalamus

Stereotactic and Functional Neurosurgery, 1985
Electrical and physiological stimulation in the periphery evokes potentials which can be recorded in the target region during stereotactic surgery. This procedure, combined with intracerebral stimulation, is commonly used as a method to verify the localization of the tip of the probe.

Preterm maturation of the somatosensory evoked potential

Electroencephalography and Clinical Neurophysiology/Evoked Potentials Section, 1996
This study investigated the maturational pattern of the cortical somatosensory evoked potential (SEP) in the preterm period. SEPs were recorded in 22 preterm neonates (27-32 weeks gestational age (g.a.), mean age 28.4 weeks g.a.; total of 46 studies). The infants were first tested at an average of 5 days.

Somatosensory evoked potentials in healthy people

Neurophysiology, 1977
The results of a study of somatosensory evoked potentials recorded in 37 healthy subjects of both sexes are described. Comparison of the results of tests on three age subgroups showed selectivity in the change in latencies and amplitudes of waves of the somatosensory responses depending on the subject's age.

Somatosensory evoked potentials in lacunar syndromes

Journal of Neurology, 1988
Parietal and prerolandic somatosensory evoked potentials (SEPs) to median nerve stimulation were recorded from 40 patients with lacunar syndromes due to CT-verified lacunar infarcts. The control group consisted of 30 age-matched normal controls. Nineteen patients showed SEP abnormalities, mainly an increase of height-covariated latency of cortical ...
