Autaptic Modulation of Electrical Activity in a Network of Neuron-Coupled Astrocyte

Abstract EN

Autapse connection is considered on a biological neuron coupled by astrocyte, and the effect of autapse driving-induced response in electrical activities is investigated.

In this paper, a simple network is developed on the Hodgkin-Huxley (HH) neuron coupled by astrocyte and the autapse effect is also considered.

The modulation of autapse connected to HH neuron can change the membrane potential by applying time-delayed feedback along a close loop.

It is found that the self-adaption of autapse driving can make the network of neuron-astrocyte generate different modes of electrical activities, and oscillating behavior of Ca2+ and IP3 setting is controlled.

This new network model can give potential understanding about self-adaption of neuron to external forcing when the coupling of astrocyte and autapse is considered.
