Model of self-oscillations in a neuron generator under the action of an active medium

Mechanisms of generation of self-oscillations in a mathematical model of a neuron embedded in an active medium have been analyzed. The processes of generation of pulsed electric activity are mediated by ionic currents through the cell membrane of the neuron, which can in turn be controlled by neuroactive substances distributed in the extracellular space. Bifurcation mechanisms of the generation and destruction of self-oscillations, as well as their characteristics, have been studied within a neuron generator model developed on the basis of neurobiological experiments.
