“…Interestingly, Barry et al have found the magnetic field, indicating that the magnetic field exists generated by action potential [1]. The exogenous magnetic field has obvious influence on the electrical activity of neurons [20] [21]. Therefore, it is a direction to study theoretically the dynamic behavior of neurons under electromagnetic induction.…”

Based on the three-dimensional endocrine neuron model, a fourdimensional endocrine neuron model was constructed by introducing the magnetic flux variable and induced current according to the law of electromagnetic induction. Firstly, the codimension-one bifurcation and Interspike Intervals (ISIs) analysis were applied to study the bifurcation structure with respect to external stimuli and parameter k 0 , and two dynamical behaviors were found: period-adding and period-doubling bifurcation leading to chaos. Besides, Hopf bifurcation was specially discussed corresponding to the transformation of the state. Secondly, the different firing patterns such as regular bursting, subthreshold oscillations, fast spiking, mixed-mode oscillations (MMOs) etc. can be observed by changing the external stimuli and the induced current. The neuron model presented more firing activities under strong coupling strength. Finally, the codimension-two bifurcation analysis shown more details of bifurcation. At the same time, the Bogdanov-Takens bifurcation point was also analyzed and three bifurcation curves were derived.
