Identification of the gain function Φ^(eff). (A) Contour plot of the identified gain function Φ^(eff)(c,ν) starting from the reference values extracted in Figure 4 (white region, Φ^(eff) < 0.5 Hz). Solid and dashed black curves, the same nullclines of the vector field as in Figures 3 and 4. (B) Identified Φ^(eff) sections at different c (see inset for color code). Black dashed line, Φ^(eff) = ν. (C) Contour plot of Φ^(eff) from mean-field theory for model parameters as in Figure 1 (white region, Φ^(eff) < 0.5 Hz). Black curves as in (A). (D) Theoretical nullcline Φ^(eff) = ν (red) versus the one from the identified G(c,ν) black, the same as in (A,C).
