Figure 10.

Weak coupling predictions compared to observations from our method. Shown are the effective coupling function (solid black curve) for the coupled system with g_syn = 0.25 mS/cm². The system does not have a stable locking mode at the values of the applied current that give rise to a 2:1 mode in the uncoupled system. Changing the applied current value for the fast neuron shifts the coupling function down. For the range of values where there was a predicted and observed 2:1 locking in the system with our method (shaded region enclosed by the dashed curves), weak coupling method does not predict such a mode. This is due to a failure to satisfy the conditions required for the weak coupling method.
