Fig. 4

One-dimensional bifurcation diagram for the swimming (black) and synchrony (red) limit cycles at varying inhibitory strength \(w_{\mathrm{ihn}}\). Blue and purple lines show two unstable limit cycles appearing at bifurcation points \(w_{3}\) and \(w_{4}\), respectively. The y-axis shows the maximum of the \(K_{f}\)-gating variable f of the left cIN for each limit cycle. Stable and unstable limit cycles are shown by continuous and dashed lines, respectively. The superscript − refers to subcritical bifurcations. Bifurcation parameter values (in nS) are the following: \(w_{1} =8.57\), \(w_{2} =2.86\), \(w_{3} =15.74\), \(w_{4} =27.6\), \(w_{5} =11.23\) and \(w_{6} =11.21\)
