Interplay between Hebbian and homeostatic timescales for different learning rules and homeostatic forces. (A) Pairwise STDP with weight dependent modification in Equation (19). Left column: convergence in the phase space (w, θ) for a fast homeostatic force (τ_Hebb = τ_homeo = 10 min, upper row), or for a slow homeostatic force (τ_homeo = 10τ_Hebb, lower row). Right column is the same, but with a stronger drive α = 1 for the homeostatic force. (B) Same as (A) for the triplet learning rule (Pfister and Gerstner, 2006), see Equation (20).
