Simulation results for a recurrent excitatory neuronal network in the high-frequency regime with heterogeneous initial synaptic strengths and ξ > 0. (A) (Left panel) Time course of the mean synaptic strength \(\bar{g}\)(t) for different standard deviations σg. (Right panel) Initial and final distribution of the synaptic strengths. (B) (Left panel) Time course of the order parameter r(t). (Right panel) Time course of the normalized number of closed loops of length 2, representing the number of bidirectional connections in the network. (C) Final coupling matrices for σg = 0.05,0.08,0.10,0.15, respectively. Network and STDP parameters are N = 200, ν = 80 Hz, \({\tau }_{{\rm{d}}}=0.5\,\,{\rm{ms}}\), τa = 1.0 ms, A+ = A− = 0.005, and τ+ = τ− = 20 ms.
