Somatosensory Evoked Potentials
1983Somato 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.

Long latency somatosensory evoked potentials
Journal of Clinical Neurophysiology, 1986Theoretically, 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, 1981Abstract 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, 1985Electrical 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, 1996This 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, 1977The 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, 1988Parietal 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 ...

Somatosensory-Evoked Potential Monitoring
2013Somatosensory-evoked potentials (SEPs) are an excellent modality for spinal cord monitoring during surgery. They cover much territory, including the peripheral, spinal, brain stem, thalamic, and cortical levels of sensory pathways. They are used for monitoring for both spinal cord and cerebral injury during various types of surgery.

Somatosensory Influence on Corticomotor Evoked Potentials
Journal of Spinal Disorders, 1988The clinical utility of corticomotor evoked potentials (CMEPs) as a method of evaluating and monitoring patients with spinal cord disorders is being intensively studied. Relatively few neuronal mechanisms responsible for waveform production are clearly known.

Somatosensory evoked potentials in Huntington's disease
Electroencephalography and Clinical Neurophysiology, 1982Scalp recorded somatosensory evoked potentials (SEPs) elicited by left and right median nerve stimulation were obtained in 21 patients with Huntington's disease (HD), 14 individuals at risk (AR) for HD, and 21 non-patient controls matched for age and sex. Although SEP abnormalities were not uniform in the HD group, no HD patient had SEPs that conformed
