| Abstract: |
| The dynamics of neuronal firing activity has important implications in understanding the pathological respiratory rhythm. Studies on electrophysiology have shown that the magnetic flow has an important influence on the firing activities of neurons. Based on the Butera neuron model, we investigate the effects of external stimulus on neuronal activities. By multi -time scale and bifurcation analysis, we study the dynamic mechanism of the generation and transition of firing patterns under the condition of external stimulus. The results show the bistable structure can be switched from one type to another by controlling the external stimulus, which means that different neuronal firing patterns will arise. Our current work gives an insight into the effects of the external stimulus on the activities of the neural network. |
