Transmission Characteristic of Unmyelinated and Myelinated Axons in Neurons
Authors: ,
Abstract: This paper describes signal transmission characteristics of axons. Unmyelinated and myelinated axons are considered for electrophysical analysis. Inductance L and capacity C per unit length, and phase velocity are given first for lossless axon. It is then presented that higher velocity and wideband signal transmission are capable under reduced C and L with large cross section and myelins. Loss and phase rotation per unit length are also given for axon with serial resistance r and parallel conductance g. Attenuation, phase rotation, and phase velocity are given for axon with loss. Long distance transmission is realized by reduction of serial resistance r and parallel conductance g along the axon. It is also presented that attenuation loss is resuced by Na+ ions distributed at the axon without myelins.
