The crab cardiac system model and its behavior. A: the three processes (arrows) and the six elementary functions (shown in semi-cartoon form) that describe them. B: representative sections of spikes (blue) and contractions (red) produced when the model was run with all six elementary functions intact (i), with the CG history kernel disabled (H' = 0; ii), and with the feedback from the muscle disabled (K' = 0; iii).
