| 摘 要： | The stochastic resonance in paced time-delayed scale-free FitzHugh-Nagumo(FHN) neuronal networks is investigated.We show that an intermediate intensity of additive noise is able to optimally assist the pacemaker in imposing its rhythm on the whole ensemble.Furthermore,we reveal that appropriately tuned delays can induce stochastic multiresonances,appearing at every integer multiple of the pacemaker’s oscillation period.We conclude that fine-tuned delay lengths and locally acting pacemakers are vital for ensuring optimal conditions for stochastic resonance on complex neuronal networks. |

| Abstract: | The stochastic resonance in paced time-delayed scale-freeFitzHugh--Nagumo (FHN) neuronal networks is investigated. We showthat an intermediate intensity of additive noise is able tooptimally assist the pacemaker in imposing its rhythm on the wholeensemble. Furthermore, we reveal that appropriately tuned delays caninduce stochastic multiresonances, appearing at every integermultiple of the pacemaker's oscillation period. We conclude thatfine-tuned delay lengths and locally acting pacemakers are vital forensuring optimal conditions for stochastic resonance on complexneuronal networks. |
