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.

"Threshold-level" multipulse transcranial electrical stimulation of motor cortex for intraoperative monitoring of spinal motor tracts: description of method and comparison to somatosensory evoked potential monitoring.

Journal of Neurosurgery, 1998
UNLABELLED Numerous methods have been pursued to evaluate function in central motor pathways during surgery in the anesthetized patient. At this time, no standard has emerged, possibly because each of the methods described to date requires some degree of

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 potential phase reversal and direct motor cortex stimulation during surgery in and around the central region.

Neurosurgery, 1996
In 99 patients with mass lesions in and around the central region, the central sulcus was intraoperatively localized with the use of somatosensory evoked potential (SEP) phase reversal.

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 ...

Incidence of sciatic nerve injury in operatively treated acetabular fractures without somatosensory evoked potential monitoring.

Journal of Orthopaedics and Trauma, 1997
OBJECTIVE The authors investigated the incidence of sciatic nerve injury associated with the operative repair of acetabular fractures without somatosensory evoked potential (SSEP) monitoring. DESIGN Retrospective case review of prospectively documented

Somatosensory-Evoked Potential Monitoring

2013
Somatosensory-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.
