Special Session 13: Nonlocally coupled dynamical systems: Analysis and applications
Contents
In this talk, I would like to review our recent results on oscillatory neural networks with spike timing-dependent plasticity. In particular, we studied the effects of independent noise and coupling on the stability of the synchronized as well as the desynchronized states. We found that the mean synaptic coupling in such systems increases dynamically in response to the increase of the noise intensity, and there is an optimal noise level, where the amount of synaptic coupling gets maximal. We discuss also the conditions, under which the spike timing-dependent plasticity (STDP) can be reduced to the phase-difference dependent plasticity.
