Dynamics Analysis of Neuron Bursting under the Modulation of Periodic Stimulation

Abstract EN

A nonsmooth neuron model with periodic excitation which can reproduce spiking and bursting behavior of cortical neurons is investigated in this paper.

Based on nonsmooth bifurcation analysis, the mechanism of the bursting behavior induced by slow-changing periodical stimulation as well as the associated evolution with the variation of the stimulation is explored.

The modulating character of the external excitation and the effect of the bifurcation occurring at the switching boundary of the vector field are presented.
