Excitation of a Neuron for Characteristic Potential Generation
Authors: ,
Abstract: This paper presents unified modelling of excitation for generation of multiple output waveforms. Unified modelling is applied to neurons generating pulse and plateau with positive and negative potentials. Electro-physical analysis is given first that a p – n junction is formed in cytoplasm when positive charges are injected into cytoplasm filled with negative charges. The junction is characterized by a depletion layer between two zones. Modelling of a neuron is given by the configuration with three zones and two depletion layers induced in cytoplasm. Equivalent circuit and response are given for amplifier and generator (oscillator) of characteristic potentials of pulse and plateau, first for positive and then for negative potential excitations. Bipolar potential generation provides a neural system with accurate and reliable processing and transmission of information.
