Abstract

Abstract. Hodgkin and Huxley were the pioneers to abstract biological neuron as an electric circuit and nerve signal as the voltage impulse. The Hodgkin-Huxley theory (Hodgkin and Huxley, 1952) has set the direction and defined the goals for much of the ensuing research in biophysics. However, in 2005, T. Heimburg and A. D. Jackson, biophysicists from Copenhagen proposed a new neural theory called Soliton theory (Heimburg and Jackson, 2005). In this theory, the nerve conduction is proposed as a density wave. In this paper, Hodgkin-Huxley and Soliton theories are described and a theoretical comparison has been carried out throughout the analysis of the theories and models.

Summary

Introduction

Nerves are the information transmitter lines from the brain to organs. The nerves are described as the bundle of discrete individual cells called neurons. These individual cells transmit the information as signals. The main parts of a neuron are the cell body (soma), signal receiving ends (dendrites), signal transmitter (axon), and connecting ends to other neurons or glands (synapses). The scientific model of the neuron was first given in electrical terms by Hodgkin and Huxley (Hodgkin and Huxley, 1952). Hodgkin and Huxley conducted the experiments on nonmyelinated giant axon of squid to study the neuronal properties. The Hodgkin-Huxley equations (Hodgkin and Huxley, 1952) are the starting point for detailed neuronal models
