Complex Dynamics of FitzHugh-Nagumo Type Neurons Coupled with Gap Junction under External Voltage Stimulation

In the present paper, we have studied the complex dynamics of a system of two nonlinear neuronal cells, coupled by a gap junction, which is modelled as a linear variable resistor. The two coupled cells are oscillators of the FitzHughNagumo type. The first cell, the “ImK-cell” is a voltage driven c...

description In the present paper, we have studied the complex dynamics of a system of two nonlinear neuronal cells, coupled by a gap junction, which is modelled as a linear variable resistor. The two coupled cells are oscillators of the FitzHughNagumo type. The first cell, the “ImK-cell” is a voltage driven cell, while the second, the “RaLa-cell” is a current driven cell. We have examined the dynamics of the coupled system in the case of bidirectional coupling. An independent voltage source gives the external stimulation. We have examined three different cases (AC, DC, AC plus DC) of the external signal. In each case we have different dynamics. Action potentials, chaotic and periodic oscillations are observed.
