Conduction Velocity in the Human Supraorbital Nerve

European Neurology, 2008
Maximal conduction velocity in the supraorbital nerve (afferent fibers for the blink reflex) has been estimated in 12 normal subjects (on the right and left side): the mean value was 41 m/s. Furthermore, this investigation was made on 23 patients with different pathologies (9 with trigeminal neuralgia with hypoesthesia, 8 with multiple sclerosis, 6 ...

The Maximization of Nerve Conduction Velocity

IEEE Transactions on Systems Science and Cybernetics, 1969
Histological and electrical examination of high-speed (myelinated) nerve fibers reveals a coaxial RC cable whose inner conductor has from 40 to 80 percent of the diameter of the outer conductor. If various reasonable engineering approximations are made, it turns out that the latter geometry corresponds to maximum conduction velocity. The model suggests

Diurnal fluctuations of human nerve conduction velocity

Acta Neurologica Scandinavica, 2009
In 14 normal subjects, sensory conduction velocity (SCV), determined at constant skin temperature, displayed diurnal fluctuations which were related to similar variations in rectal temperature. Control of surface limb temperature in routine EMG does not completely obviate the variations induced by the body temperature cycle. Diurnal fluctuations should

Nerve Conduction Velocity During Hypothermia in Man

Anesthesiology, 1966
Alterations in peripheral nerve impulse conduction during cooling were investigated in 7 surgical patients. A significant association between maximum conduction velocity and mean nerve temperature was found for peroneal nerve. Conduction velocity fell from 49.6 m./second at 35.5° C to one-half (25.9 m./second) at 23.5° C.

Nerve conduction velocities in hyperlipidemic patients.

Neuro endocrinology letters, 2013
Metabolic disease affect all systems in the body, including the peripheral nervous system, but there is a controversy as whether to consider hyperlipidemia is a cause of peripheral neuropathy. The aim of the present study was to evaluate whether hyperlipidemic subjects with no clinical symptom or sign of peripheral neuropathy showed nerve conduction ...

Conduction velocity in the ulnar nerve in hemiplegic patients

Journal of the Neurological Sciences, 1971
Conduction velocities of the motor fibers in the ulnar nerve between the elbow and wrist were measured in 25 patients with hemiplegia of 1–50 days' duration and a mean age of 67.0 years. The “fast” motor conduction velocity was within the normal range in this age group, and there was no statistical difference between the paralyzed side (50.4±1.44 m/sec)

Selective measurement of digital nerve conduction velocity

Journal of Orthopaedic Science, 2001
We developed a new method to measure the nerve conduction velocity of a single digital nerve. In 27 volunteers (27 hands), we separately stimulated each digital nerve on the radial and ulnar sides of the middle and ring fingers. A double-peaked potential was recorded above the median nerve at the wrist joint when either the radial-side nerve or the ...

On the velocity of conduction in nerve fibers with saltatory transmission

The Bulletin of Mathematical Biophysics, 1949
Using an electrical model to represent certain features of a nerve fiber together with a one-factor theory of excitation, an expression is obtained for the velocity of propagation of a nerve impulse along a nerve fiber exhibiting saltatory transmission. The velocity shows a maximum with respect to internodal length.

Nerve Conduction Velocity-Reply

JAMA, 1961
To the Editor:— Dr. Hodes' premise is that the conduction velocity of motor fibers in poliomyelitis patients is reduced, presumably because of selective destruction of large motor neurons. This premise was based on determinations in 26 chronic patients (presumptive diagnosis).

Conduction velocities along course of ulnar nerve

Journal of Applied Physiology, 1964
The left ulnar nerve was tested on 20 normal subjects on two occasions several weeks apart to determine the motor velocities along various points over the course of the ulnar nerve. Analysis showed that there is no practical difference between proximal and distal motor velocities of the normal ulnar nerve.
