Effects of pulse-width on dynamics of spiking neurons with periodic base signal

Rich dynamics can be achieved by spiking neuron circuit (SNC) with periodic base signal. In view of the existence of pulse-width of spiking, the influences of relative pulse-width (i.e. the ratio of pulse-width to the period of base signal) on both single spiking neuron and two pulse-coupled spiking neurons circuits (PCSNC) are investigated. Results show that the wider the pulse-width is, the more effects it has on the single SNC. Moreover, the existence of pulse-width can cause rich phenomena generated by PCSNC as well as alteration of parametric range of chaos and period, which can help to instruct the implementation of pulse-coupled neuron networks on chips.
