Prevention of runaway dynamics in the model depends on the slope of weight dependence of heterosynaptic plasticity. A1–A3, Example relations between heterosynaptic weight changes and initial weights for slope factors (Sf) 10, 40, and 70, as indicated, and initial and final distributions of weights of two groups of synapses in models implementing these relations. B, Dependence of the final weights (mean ± SD) of two groups of synapses on the slope of weight dependence of heterosynaptic plasticity, as shown on the right (Eq. 11, SlopeFactor). Black are mean ± SD of initial synaptic weights. Two groups of synapses had STDP rules as in Figure 6 model.
