EFFERENT NERVE FIBERS OF COCHLEA
Archives of Otolaryngology - Head and Neck Surgery, 1954ALTHOUGH the sensory terminations of the cochlear nerve have been well known since the outstanding research of Retzius, Ramon y Cajal, and, more recently, Lorente de No, other systems of fibers in the auditory apparatus are far from being perfectly understood.

Feedback controlled nerve fiber impalement
Electroencephalography and Clinical Neurophysiology, 1981A device has been described for the automatic impalement of nerve fibers. Although developed specifically for that task, the technique can be applied for intracellular recording from other cells or processes. The basis of the techniques is to use the cell membrane potential to stop the advance of a fast moving microelectrode.

Retinal Nerve Fiber Layer Measured by Heidelberg Retina Tomograph and Nerve Fiber Analyzer
European Journal of Ophthalmology, 2005Purpose To compare retinal nerve fiber layer (RNFL) thickness measured by Heidelberg retina tomograph (HRT) and nerve fiber analyzer (GDx). Methods Twenty eyes of 20 consecutive healthy subjects were recruited for this study. Each subject had a normal visual field and a normal optic nerve head, which was assessed by slit-lamp biomicroscopy using a 90 ...

Beading of myelinated nerve fibers
Experimental Neurology, 1965Abstract The phenomena of beading upon stretching was studied in nerve fibers of freeze-substituted nerves. Beading appears rapidly along the length of the mammalian nerve. Nerve fibers of frogs kept at low temperatures have a crenated shape in cross section and show wrinkling in longitudinal section, but no beading is produced upon stretching them ...

Ischemic Degeneration of Nerve Fibers
Archives of Neurology, 1960Direct evidence that nerve fiber degeneration may follow occlusion of groups of regional vasa nervorum, although provided by the experiments of Okada 17 (1905), Adams 1 (1943), Durward 11 (1948), and Roberts 19 (1948), has been scanty, and the conclusions to be drawn from the highly variable, but mainly negative, results of these experiments are ...

The Journal of Membrane Biology, 1977
The hydrostatic (Lp) and osmotic (LPD) filtration coefficients and the efflux rates of tritiated water were measured in the giant axon of Loligo vulgaris. The Lp was 8 to 14 X 10(-8) cm/sec/cm H2O and the LPD was two orders of magnitude smaller (3 to 6 X 10(-10) cm/sec/cm H2O).

Morfologiia (Saint Petersburg, Russia), 2003
The paper presents a critical review of various current concepts of the structure and kinetics of unmyelinated nerve fiber. A classification of nerve fibers, different from the earlier ones, is proposed, that demonstrates not only the morphological fiber types, but also the kinetics of their reversible transition stages from non-glial to myelinated ...
