Figure 4.
Panels (a,b) show steady-state behaviour of (3.1) for identical initial conditions but with two different coupling strengths. Note that both neurons are identical. As shown in the analysis to follow, the steady state in simulations for ρ = 0.06 mS cm−2 results from a saddle node bifurcation. This behaviour can neither be explained nor predicted with standard phase reduction. (Online version in colour.)
