Effect of height on nerve conduction velocity

Neurology, 1982
The effect of height on nerve conduction velocity (NCV) was studied in 41 normal subjects. Peroneal and sural NCV correlated inversely with height and with estimated axonal length, whereas median motor and sensory NCV failed to show any significant relationship to height.

Nerve Conduction Velocity

Archives of Internal Medicine, 1972
To the Editor. —The article, "Nerve Conduction Velocity in the Assessment of Hypertension" by Viskoper, Chaco, and Aviram (Arch Intern Med 128:574-575, 1971) concluded that "nerve conduction velocity can provide us with an objective measurable index of the severity of hypertension." Although one might think that this could be done more easily with a ...

Spinal sympathetic conduction velocity in humans

Journal of the Autonomic Nervous System, 1988
Simultaneous micro-electrode recordings of muscle sympathetic activity were made in the radial nerve at the mid-humerus level and the peroneal nerve at the fibular head in 8 healthy subjects. Sympathetic impulses occurred spontaneously in multi-unit bursts time-locked to the cardiac rhythm.

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

Ultrasound and Conduction Velocity

Physical Therapy, 1984
To the Editor: I commend the educational practice of schools that encourage and support simple research projects by students. The experience of identifying a problem, designing an appropriate experiment to study it, performing the experiment, gathering and analzying the data, and finally reporting the results in a logical and scholarly manner, all ...

Polarity Correlator for Conduction Velocity Measurement

IEEE Transactions on Biomedical Engineering, 1984
Techniques for the estimation of skeletal muscle fiber conduction velocity are of considerable interest. These techniques use, in general, some form of cross correlation or zero-crossing analysis. Cross correlation is a straightforward method of conduction velocity estimation, however, it is difficult to realize low-cost real-time processors.

Axonal conduction velocity and perikaryal size

Experimental Neurology, 1975
Abstract The recent identification of brisk-transient units with alpha cells in the cat's retina provided a direct opportunity to test the widely held belief that larger cells give rise to larger axons, and smaller to smaller. Alpha-cell perikarya increase substantially in size over the first 2 mm from the center of the area centralis.

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 ...

Conduction velocities in the corticospinal tract of the horse

Experimental Neurology, 1967
Abstract An investigation of the corticospinal tract of the horse ( Equus caballis ) was made by stimulating the pyramids electrically and recording neural activity evoked in peripheral motor nerves. Conduction velocities of the peripheral nerves were determined and the length of the nerves measured from point of stimulation of the pyramids to exit ...

Proximal and Distal Conduction Velocities in Neuropathies

Electroencephalography and Clinical Neurophysiology, 1983
Conventional methods for measurements of motor and sensory conduction have proved to be useful for evaluating function of motor and sensory nerve fibres in distal segments of peripheral nerves. The results, expressed as conduction velocity in meters per second and distal latency in milliseconds, provide numerical data which are of considerable clinical
