Title: Simulations of conduction in uniform myelinated fibers. Relative sensitivity to changes in nodal and internodal parameters. Author: Moore JW, Joyner RW, Brill MH, Waxman SD, Najar-Joa M. Journal: Biophys J; 1978 Feb; 21(2):147-60. PubMed ID: 623863. Abstract: Conduction of impulses in myelinated axons has been studied by a new method of computer simulation. The contributions of nodal and internodal characteristics and parameters were examined. Surprisingly, the conduction velocity, theta, was found to be quite insensitive to the nodal area or the exact description of its excitable processes. The conduction velocity also is relatively insensitive to the internodal length but much more sensitive to the myelin capacitance and axoplasm conductance. Qualitative change in theta with temperature depended on which temperature-sensitive parameters were included in the simulation.[Abstract] [Full Text] [Related] [New Search]
