Subtotal Aplasia of Myelinated Nerve Fibers in the Sural Nerve*

Neuropediatrics, 1993
Thus far, only very few cases with neuronal maldevelopment in the peripheral nervous system have been reported (Table 1). The present sporadic case manifested itself with peripheral sensorimotor polyneuropathy in early infancy. Clinical findings included pareses and hypaesthesia of distal extremities and severely reduced nerve conduction velocities ...

Physiology and pathophysiology of myelinated nerve fibers

2013
The chief role of the axon is that of impulse conduction, which depends on the electrical cable structure and voltage-dependent ion channels of the axonal membrane. Over recent decades, the development of specialized techniques such as patch clamping and site-directed mutagenesis have established the contribution of neuronal ion channel function to the

Myelinated Retinal Nerve Fibers

Journal of Clinical and Medical Images, Case Reports, 2023

Myelinated nerve fiber antenna model activation

2016 24th International Conference on Software, Telecommunications and Computer Networks (SoftCOM), 2016
A myelinated nerve fiber is modeled as a straight thin wire antenna and stimulated by a current generator at the fiber beginning. The model is based on the corresponding homogenous Pocklington integro-differential equation for the perfectly conducting wire in a lossy unbounded homogenous space, where the activated node of Ranvier is modeled as a thin ...

Antenna model for passive myelinated nerve fiber

2015 23rd International Conference on Software, Telecommunications and Computer Networks (SoftCOM), 2015
A myelinated nerve fiber, stimulated by a current generator at the fiber beginning, is modeled as a straight thin wire antenna. The model is based on the corresponding Pocklington integro-differential equation for the perfectly conducting wire in a lossy unbounded homogenous space.

Measurement of the Action Potential of Myelinated Nerve Fiber

American Journal of Physiology-Legacy Content, 1955
THE PEAK VALUE of the action potential of the vertebrate myelinated fiber has been previously recorded by a number of investigators. (1-5 and others). Values range from about 60-155 mv depending on the method employed. These methods may be divided into three general categories.

A model of injury potential for myelinated nerve fiber

2015 37th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC), 2015
Excellent models have been described in literatures which related membrane potential to extracellular electric or magnetic stimulation and which described the formation and propagation of action potentials along the axon, for both myelinated and nonmyelinated fibers.

Progression of Retinal Nerve Fiber Myelination in Childhood

American Journal of Ophthalmology, 1994
Myelination of the visual pathway has been demonstrated to occur by as early as 32 weeks of gestation and continues for several years into early childhood. In most cases, the process of myelination does not extend beyond the lamina cribrosa. We studied a boy with progressive myelination that extended beyond the lamina cribrosa to the retinal nerve ...

Density of myelinated nerve fibers in the chinchilla cochlea

The Journal of the Acoustical Society of America, 1982
Baseline values for the density of myelinated nerve fibers at 11 locations in the chinchilla cochlea were obtained as a prerequisite for studying the relationship between sensory cell degeneration and spiral ganglion cell loss. Myelinated nerve fibers were counted within the osseous spiral lamina near the habenulae perforata. The data were expressed as

In Vivo Studies of Myelinated Nerve Fibers

1964
Publisher Summary From the standpoint of both structure and function the myelinated nerve fiber is a highly specialized component of the nervous system. It represents a very intimate association of a nerve cell process with a satellite myelinating cell.
