FIG. 17.

An illustration of how changes in β₂ and β₅ significantly change the oscillation frequency. Here β₂ and β₅ are divided by a factor of 2. Other parameter values are the same as in Figure 15. Compare with Figure 15. (a) The dimensionless concentration of ${\text{G}}_{\text{i}}^{\prime }$. (b) Five times the intracellular cAMP concentration [cAMP_i] (solid line) and the extracellular cAMP concentration [cAMP_o] (dashed line).
