Figure 2.

A temperature-sensitive model of the pyloric pacemaker kernel. A, Schematic diagram of the four-compartment conductance-based model, with voltage-dependent currents listed. B, Six maximal conductance sets that produce biologically realistic and nearly identical bursting patterns at 11°C. Left, Voltage traces for each maximal conductance set (red traces = AB soma; blue traces = PD soma). Right, Corresponding parameters for each maximal conductance set (normalized to parameters for set #0). Kd(a) and Kd(s), respectively, indicate the maximal conductances of delayed rectifier current in the axonal and somatic compartments.
