Abstract(in Japanese) (See Japanese page)
Abstract(in English) An additive rule of spike-timing-dependent synaptic plasticity (STDP) automatically achieves synaptic competition and activity regulation, where synaptic balance is moderately regulated to control the post synaptic activity [1]. On the other hand, a multiplicative STDP rule can not achieve the synaptic competition nor the synaptic regulation [2], [3]. It is not clear what type of STDP rules can achieve synaptic regulation and how it is related to synaptic competition. Here we clarify the mechanisms of synaptic regulation and propose multiplicative STDP rules which can acheive synaptic regulation.
