Biochemical model of five signaling pathways (3 activated by cAMP and 2 activated by calcium) leading to ERK activation during L-LTP induction. Simulations show that calcium and cAMP work synergistically to activate ERK and that stimuli given with large inter-trial intervals activate more ERK than shorter intervals. Epac and RasGRF pathways contribute to early dynamics and PKA and CaMKII contribute to late dynamics of ERK activation.
