BCPNN dynamics in two different representations for an example spike train. (A) Presynaptic traces according to the original model formulation (Z_i, E_i, P_i), as expressed in Equations (7–9). (C) “Exponential” traces Z^*_i, E^*_i, P^*_i used for the analytical II solution with minimal number of calculations, according to Equations (32–34). Dashed lines in A and C denote spike response kernels, i.e., responses to a single spike. (B) Transformation between the two different representations (Equations 29, 30, 46).
