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 $w_6=11.21$
