Figure 4

Time evolution of the average effective excitatory (violet) and inhibitory (green) synaptic weights \({\overline{w}}^{(exc)}\) and \({\overline{w}}^{(inh)}\), as defined by (6). The network contains 320 and 80 excitatory and inhibitory neurons. Also shown is the average balanced weight (red, enlarged in the insets), given by \(4{\overline{w}}^{(exc)}+{\overline{w}}^{(inh)}\). Left: With short-term plasticity. Right: Without short-term plasticity, namely for φ j  ≡ 1 and u j  ≡ 1.
