PROPAGATION OF ACTION POTENTIAL IN NEURON - A NEW APPROACH WITH MAGNETIC EFFECT OF CURRENT

The central nervous system CNS acquired the control of the human body by to and fro transformation of information. The information is transferred from one neuron, the basic element of CNS to another neuron as electrical signals, called action potential. The axon a part of neuron acts as the medium for this propagation. The magnitude and duration of action potential remains the same throughout the propagation path. The process of propagation is termed as saltatory transmission or hopping. (Saltare means jump in Greek). This can be termed as lossless transmission in electrical engineering terms. At present, neuron is modeled as resistance-capacitance (RC) circuit in Hodkin Huxley model. To explain the lossless transmission, the transmission channel is to be modelled as an LC (Inductance- capacitance) circuit or a compensated RLC (resistance-Inductance-Capacitance) circuit. The current model can be changed to this form by the addition of an inductance, which is equivalent to the self-induced inductance in the neuron due to the flow of current through the neuron.
