Improvement of Izhikevich´s Neuronal and Neural Network Model

To enhance the veracity of Izhikevich´s neuronal model and plausibility of Izhikevich´s neural network model, we revised Izhikevich´s neuronal model, deleted neurons´ synaptic connections to themselves and established the description of short-term depression and time delay along axon in Izhikevich´s neural network model. The simulation results with the improved neuronal model show it is more efficient and accurate for computation, the improved neural network model spikes with less synchronicity.
