Unmedullated Fibers Originating in Dorsal Root Ganglia
The compound action potential of the unmedullated fibers arising from dorsal root ganglia, as recorded in cat skin nerves after conduction of simultaneously initiated impulses, shows among its components a temporal dispersion corresponding to velocities between 2.3 and 0.7 M.P.S. The maximum representation of the component velocities is at about 1.2 M.P.S. On both sides of the maximum the repre...
متن کاملThe Postspike Positivity of Unmedullated Fibers of Dorsal Root Origin
The positivity following the spike in the action potential of unmedullated nerve fibers of dorsal root origin (d.r.C) has been shown to be homologous with the first positive potential (P(1)) of other varieties of nerve fibers. Thus it is only through the large size of the positivity that this group of nerve fibers is set apart from other groups. New findings accentuate and make more explicit th...
متن کاملProperties of Dorsal Root Unmedullated Fibers on the Two Sides of the Ganglion
As an aid in the interpretation of the physiological properties of unmedullated nerve fibers, particularly those having their cells of origin in the dorsal root ganglia, more precise information about their morphology has been acquired through employment of the electron microscope. The appearance of the fibers in the skin nerves is described, with special reference to the structure of their she...
متن کاملPeroxisomes in dorsal root ganglia.
Bodies with the morphologic and cytochemical characteristics of peroxisomes have been identified in the satellite and Schwann cells of rat dorsal root ganglia. They are membrane-delimited, round or oval structures which contain a moderately electron-dense matrix but lack a crystalline core. On incubation of the tissue in a cytochemical medium for demonstration of peroxisomes, these bodies show ...
متن کاملPaclitaxel-Resistant Neurons in Dorsal Root Ganglia
Paclitaxel is an antineoplastic drug, and its usage is often limited by severe peripheral polyneuropathy characterized by symptoms in remote extremities. It is suggested that subpopulations of dorsal root ganglion (DRG) neurons are impacted functionally and/or structurally. In this study, the neurotoxic effect of this drug in cultured rat DRG neurons was analyzed by measuring their neurite leng...
