Ideal STDP characteristics. (a) Schematic image of the STDP curve. (b) Schematic images of the pre-/post-spikes and superimposed spikes at Δt ≈ τC and Δt, at which ΔG ≈ ΔGmax for three spike types (TT, RT, and RR types). |Vpeak| is assumed to be under the condition 1/2|Vth| ≤ |Vpeak| < |Vth|. (c) Summary of the functions of |Vs|, |Vsave|, and τC for the three spike types.
