  It is well-known that the electrical activities of neurons are induced by a
wide variety of external factors. This work considers the effect of
electromagnetic induction on improved denatured Morris-Lecar neuron model. The
dependence of dynamical behaviour of the original denatured Morris-Lecar model
on parameters is addressed through numerical bifurcation analysis. This allows
us to explore the changes in dynamics of the model qualitatively as parameters
are varied. Then we investigate the effects of external periodic current and
electromagnetic flux on the dynamical properties of the improved denatured
Morris-Lecar neuron model. Different types of dynamical behaviour, ranging from
regular periodic spiking to complex bursting, are found when the multiple
parameters are varied simultaneously. The improved model could be applied to
research where simple models are required for physiological and
pathophysiological responses in neurons.
