Bifurcation analysis of a neuron having L-type calcium current

摘要

As there are many parameters in neuron models it is important to choose an appropriate parameter set such that calculations with an expected specific outcome become successful. The bifurcation diagram of a neuron with L-type calcium current is obtained with respect to the applied current. In order to gain insight into the dynamics of the system the variation of the bifurcation diagrams are investigated by changing the conductivity of the channel through which passive ions flow. The dependency of the frequencies of the periodic solutions on the applied current is obtained by considering various channel conductivities. State portrait is drawn and the variation of the current values at Hopf bifurcation points with respect to channel conductivity is found.
