Dependence of wave properties on pump strengths with gap junctions. Shown, as a function of and , are (A) the number of cells whose voltage exceeds −40 mV, (B) latency (time until one of the neuron’s membrane potential reaches −40 mV), (C) wave speed, and (D) duration of depolarization at cell V24. Here = 1, N = 5, and K+ is injected at a rate of 5 mM/s. To see this figure in color, go online.
