Interplay between Hebbian and homeostatic timescales for pairwise STDP. (A) Evolution of the weight w and the running estimate θ of the post-synaptic firing rate as function of time, for τHebb = τhomeo = 10 min and various gain α for the heterosynaptic scaling. Insets shows the trajectory in the phase space (w, θ). (B) Same as (A) with a slower homeostatic scaling: τhomeo = 10 τHebb = 100 min.
