TLDR
Somatosensory evoked potentials (SEPs) were elicited by stimulation of the right posterior tibial nerve at the ankle in 20 experiments on 18 normal adults and several positive far fields with widespread scalp distribution and stationary latencies have been identified.About:

TL;DR: Technical advice is given, normative values are reported, and special clinical applications of somatosensory-evoked potentials are discussed, which are drawing increasing interest.
Journal ArticleDOI
A method of monitoring function in corticospinal pathways during scoliosis surgery with a note on motor conduction velocities.
TL;DR: Spinal cord potentials produced by high voltage electrical stimulation of the scalp over the motor cortex were recorded intraoperatively from bipolar electrodes inserted into the epidural space of patients undergoing corrective surgery for scoliosis to be a useful adjunct to conventional monitoring of the sensory pathways during surgery.

Color imaging of parietal and frontal somatosensory potential fields evoked by stimulation of median or posterior tibial nerve in man
TL;DR: Somatosensory evoked potentials to median or fingers or posterior tibial nerve stimulation were recorded with earlobe reference in normal young adults with characteristic focal distribution suggesting that they reflected one or more generators in cortical areas.
Journal ArticleDOI
Principles and pitfalls of nerve conduction studies.
TL;DR: The fundamental principles and the changing concepts of nerve stimulation techniques are reviewed, and the proper application of these techniques in the differential diagnosis of peripheral nerve disorders are discussed.
Journal ArticleDOI
Characterizing the Cortical Activity through Which Pain Emerges from Nociception
TL;DR: The findings suggest that the N1 wave represents an early stage of sensory processing related to the ascending nociceptive input, whereas the N2 and P2 waves represent a later stage of processing related, directly or indirectly, to the perceptual outcome of this nocICEptive input.

TL;DR: Early somatosensory evoked potential components to median nerve or finger stimulation were recorded with non-cephalic references in normal young adults to identify spinal entry time with the onset of the neck N11 or scalp P11 and suggest that FF3-FF4 are generated in medial lemniscus rather than above the thalamus.

TL;DR: The changes associated with normal aging have been confirmed and extended and a new widespread component N18 was identified and shown to be generated below the cortex.

TL;DR: The use of 14 simultaneous recordings including a series of pre- and post-vertebral electrodes clearly identified two distinct generators for the spinal SEP components to median nerve stimulation: a presynaptic generator which ascends the dorsal column (N 11 ) and a postsynaptic fixed generator in the dorsal horn of the cervical spinal cord (N 13 -P 13).

Spinal evoked response: peripheral nerve stimulation in man.
TL;DR: In 3 patients with spinal cord lesions clinically judged to be complete, responses caudal to the lesion were similar to those recorded in normal subjects, consistent with the interpretation that these potentials arise in the dorsal roots of the cauda equina and in spinal cord afferent pathways.

Neural generators of N18 and P14 far-field somatosensory evoked potentials studied in patients with lesion of thalamus or thalamo-cortical radiations
TL;DR: It is proposed that N18 reflects several deeply located generators in brain stem and/or thalamus whereas N20 represents the earliest cortical response of the contralateral post-central receiving areas.
