| Abstract(in English) | Recent biological experimental findings have shown that synaptic plasticity depends on the relative timing of the pre- and post-synaptic spikes and this is called "Spike Timing Dependent Plasticity (STDP)". Many authors have claimed that the precise balance between Long Term Potentiation (LTP) and Long Term Depression (LTD) of STDP is crucial in storing spatio-temporal patterns. In the brain, it is inconceivable to maintain the balance precisely. We discuss the retrieval properties of spatio-temporal patterns in an associative memory network involving the imbalance between LTP and LTD. We analytically show that a network containing a finite number of neurons becomes robust against this imbalance. |
