Modeling and Simulation of Input Signal of STDP Synaptic System

Spike-timing-dependent plasticity(STDP) mechanism is one of the important mechanisms to study the connection of brain neural network, and it is also necessary to take into account the mechanism when do neural modeling. The reasonable modeling and simulation of the STDP synaptic system input signal is a prerequisite for obtaining STDP synaptic system that more accord with biological mechanism. In this paper, two important input signals, glutamic acid signals and back propagating dendrictic signals of STDP synaptic system were simulated by molecular dynamic diffusion model and Hodgkin-Huxley model. The simulation results are consistent with the signals under the actual physiological mechanism.
