Abstract:

Nociceptive information is transmitted from the periphery to the cerebral cortex mainly by action potential (AP) conduction in nerve fibers and chemical transmission at synapses. Although this nociceptive transmission is largely inhibited at synapses by analgesics and their adjuvants, it is possible that the antinociceptive drugs inhibit nerve AP conduction, contributing to their antinociceptive effects. Many of the drugs are reported to inhibit the nerve conduction of AP and voltage-gated Na+ and K+ channels involved in its production. Compound action potential (CAP) is a useful measure to kn

Abstract One hundred seventy patients with radial nerve disorders were reviewed at the Louisiana State University Medical Center over a 15-year period. Of these, 32 had involvement of the posterior interosseous nerve exclusively. Findings included weak wrist extension with a radial drift, inability to extend the fingers, paralysis of thumb extension, and weak thumb abduction. Causes included entrapment at the arcade of Froshe (14 patients), laceration (6 patients), fracture (6 patients), compression or contusion (3 patients), and loss associated with tumor (3 patients).

We observed nerve excitations on bullfrog sciatic nerves by an optical stimulation using a Holmium YAG (Ho:YAG) laser with the laser power over 2.0 [W]. The laser power was higher the amplitude of the action potential was bigger. However, when the laser power over 10.0 [W], the laser gave damage to the sciatic nerve and the action potential decreased. Not only the action potential was evoked by the high temperature but also the sciatic nerve was damaged by an overlarge temperature. These results show the possibility that the single wavelength laser can use to position estimation of epileptogen

Abstract:

The Hodgkin-Huxley model of nerve pulse propagation relies on ion currents through specific resistors called ion channels. We discuss a number of classical thermodynamic findings on nerves that are not contained within this classical theory. In particular striking is the finding of reversible heat changes, thickness and phase changes of the membrane during the action potential. Data on various nerves rather suggest that a reversible density pulse accompanies the action potential of nerves. Here, we attempted to explain these phenomena by propagating solitons that depend on the presence of coop

Abstract OBJECTIVE Obstetric brachial plexus lesions (OBPLs) are caused by traction to the brachial plexus during labor. Typically, in these lesions, the nerves are usually not completely ruptured but form a “neuroma-in-continuity.” Even in the most severe OBPL lesions, at least some axons will pass through this neuroma-in-continuity and reach the tubes distal to the lesion site. These axons may be particularly prone to abnormal branching and misrouting, which may explain the typical feature of co-contraction. An additional factor that may reduce functional regeneration is that improper centra

BACKGROUND: Peripheral nerve stimulation has been used to treat overactive bladder.

The action potential (AP) conduction in nerve fibers plays a crucial role in transmitting nociceptive information from the periphery to the cerebral cortex.

The compound action potential (CAP) recorded from a bundle of nerve fibers is a guide for knowing if analgesics affect nerve AP conduction.

Methods: The study was performed with 21 Crohn’s disease (Group 1) patients, 24 Ulcerative Colitis (Group 2) patients without clinical peripheral neuropathy and 28 healthy participants (Group 3). Each patient group underwent electrophysiological conduction studies. The findings were analyzed statistically. Resu

Abstract:

Purpose. Although many surgeons have anecdotally described reversing the polarity of the autograft with the intent of improving regeneration, the optimal orientation of the autogenous nerve graft remains controversial. The aim of this study was to compare (1) the outcomes of orthodromic and antidromic nerve grafts to clarify the effect of nerve graft polarity and (2) the outcome of either form of nerve grafts with that of nerve repair. Methods. In 14 of the 26 rabbits used in this study, a 1 cm defect was made in the tibial nerve. An orthodromic nerve graft on one side and an antidromic nerve

<abstract> <p>The nerves in the skin surface of the foot are comprised of unmyelinated smaller somatic nerves and larger myelinated sensory nerves. Current diagnostic methods are unable to evaluate combined nerve conduction velocity (NCV) from both unmyelinated smaller somatic nerve (USSN) and myelinated larger nerves (MLN) respectively. Computational models may provide an alternative tool to determine the NCV of the combined nerve. Therefore, a combined functional dorsal nerve model (CFDNM) of the various dorsal nerves along with its associated nerve ending of the human foot is pr

Object A typical finding in supraclavicular exploration of infants with severe obstetric brachial plexus lesions (OBPLs) is a neuroma-in-continuity with the superior trunk and/or a root avulsion at C-5, C-6, or C-7. The operative strategy in these cases is determined by the intraoperative assessment of the severity of the lesion. Intraoperative nerve action potential (NAP) and evoked compound motor action potential (CMAP) recordings have been shown to be helpful diagnostic tools in adults, whereas their value in the intraoperative assessment of infants with OBPLs remains to be determined.

We recently reported that intravenous vasopressin in anesthetized rabbits facilitates baroreflex inhibition of lumbar sympathetic nerve activity. The purpose of this study was to determine the possible sites of this facilitation. We found that intravenous infusion of vasopressin (16-32 mU X kg-1 X min-1) caused greater inhibition of lumbar sympathetic nerve activity than did phenylephrine for a given increase in aortic baroreceptor activity, suggesting a "central" action of vasopressin. A central action was supported also by the observation that the carotid baroreflex inhibition of lumbar symp

Abstract This report introduces the technique of orthodromic neurography for monitoring of facial nerve function during operation in the cerebellopontine angle. By stimulation of the intracisternal segment of the facial nerve, a compound nerve action potential with amplitudes of 15 to 480 μV can be recorded extracranially from the nerve near the stylomastoid foramen after 0.95 to 2.27 ms. Usually there is no need for signal averaging, and the method is independent of the effect of muscle relaxants.

✓ Many spinal nerve roots injured due to stretch or other types of lesions are not reparable. Some spinal nerves might be repaired if they could be exposed in their intraforaminal course. A posterior subscapular approach for a more lateral exposure of the brachial plexus was combined with a facetectomy to expose intraforaminal nerves in a series of Macaca rhesus monkeys. This approach exposed a 6- to 10-mm segment of spinal nerve not approachable by a more classic anterior operation. Sural grafts were placed from the dural exit of the spinal nerves to the cord level of the plexus. Nine survivi

OBJECTIVEIntraoperative nerve action potential (NAP) recording is a useful tool for surgeons to guide decisions on surgical approaches during nerve repair surgeries. However, current methods remain technically challenging. In particular, stimulus artifacts that contaminate or mask the NAP and therefore impair the interpretation of the recording are a common problem. The authors’ goal was to improve intraoperative NAP recording techniques by revisiting the methods in an experimental setting.METHODSFirst, NAPs were recorded from surgically exposed peripheral nerves in monkeys.

Bilateral nerve cable graft repairs were made in the sciatic nerves of Wistar rats. One group of repairs was treated locally with triamcinolone acetonide (0.5 mg), one group was exposed to the systemic effects of the drug, and one group was left untreated. Nerve regeneration was measured by nerve-stimulated muscle twitch strength, as well as several electrophysiologic parameters of the compound action potential conducted through the graft. Results suggest that nerve regeneration through an autogenous graft is significantly improved by local treatment with triamcinolone acetonide. Further studi

SUMMARY The peripheral nerve of the hen has become an increasingly important animal model in studies of peripheral neuropathy, especially that induced by organophosphorus agent exposure. However, few electrophysiologic studies have been performed, and few data on normal peripheral nerve function exist. The purpose in the present study was to measure the characteristics of the compound action potential of peripheral nerves of the healthy hen. The results showed that conduction velocities of the tibial and the sciatic nerves were 41 m/s and 60 m/s, respectively. The relative refractory period wa
