Simulation results for a recurrent excitatory neuronal network in the high-frequency regime with heterogeneous firing frequencies and ξ > 0. (A) (Left panel) Time course of the mean synaptic strength \(\bar{g}\)(t) for different standard deviations \({\sigma }_{\nu }\). (Right panel) Distribution of the firing frequencies and the final 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 σν = 0.01, 0.02, 0.03, 0.04 Hz, respectively. Network and STDP parameters are N = 200, \(\bar{\nu }\) = 80 Hz, τd = 0.5 ms, \({\tau }_{{\rm{a}}}=1.0\,\,{\rm{ms}}\), A+ = A− = 0.005, and τ+ = τ− = 20 ms.
