英文摘要	Based on the FitzHugh-Nagumo (FHN) neuron model, the effects of autapse with constant or time-periodic coupling intensity on signal transmission are investigated by calculating the Fourier coefficient Q for quantitatively characterizing the efficiency of the signal transmission. In the case of constant autaptic coupling intensity, the dependencies of Fourier coefficient Q on autaptic coupling intensity sigma present bell-shaped curves and when the autaptic time delay is approximately multiple of the period of the sub-threshold external periodic signal, the maximums of Fourier coefficient Q are obtained at moderate autaptic coupling intensities . Moreover, with the increase of autaptic coupling intensity , autaptic time delay-induced peaks become more abruptly and narrow but the height of peaks increases.This suggests that autapse may play active roles to effectively improve the efficiency and time precision of signal transmission. In the case of autapse with time-periodic coupling intensity, when autaptic coupling intensity oscillates with appropriate speed (neither too fast nor slowly), autapse cannot significantly improve the efficiency of signal transmission, but can significantly broaden the valid ranges of parameters, implying that the plasticity of autapse may improve the adaptive capacity of neurons.
