| Abstract(in English) | So far, changes in synaptic strength have been modeled as assuming that decided based on an absolute level of the calcium concentration. However, it has been pointed out not to be able to reproduce the properties of the spike-timing-dependent plasticity (STDP) by such a model. In this study, we present a model for synaptic plasticity based on the difference between the calcium inflow caused by pairing of presynaptic firing and postsynaptic firing and the linear summation of the calcium inflows caused by presynaptic firing and postsynaptic firing, and examine it by simulation experiment using NEURON simulator. It is shown that the timing property and the dependence on initial synaptic strength of STDP are reproduced using this model. In addition, we show that it is able to be important for the dependence on initial synaptic strength that NMDA conductance has some value even when AMPA conductance has the value of almost 0. |
