Simulated transient voltage characteristics during plasticity induction for (a) causal and (b) anti-causal spike patterns. The transient FG voltage following the first spike for both causal and anti-causal cases is plotted in (c) and (d), respectively. Given the spike pattern, the state variable is continuously elicited as shown in (e) and (f) and consequently alters the storage FG voltage (V m) [(g) and (h)], respectively. Eventually, synaptic weight V w evolves as plotted in (i) and (j), indicating potentiation and depression, respectively.
