Stability of the attractors of after symmetry breaking (A) Projection of the three stable limit cycles (SwC̅, SyC̅ and $\overline{2-\mathrm{SyC}}$) to the phase plane of dINs voltages and zoom of selected regions (black boxes). The green diagonal line shows the loss of mid-line symmetry of the stable limit cycles. The vector of parameters ($w_{\mathrm{inh}},w_{\mathrm{ampa}},w_{\mathrm{nmda}},\mathrm{\Delta },d$) used for the SwC̅ case are ($60,10,10,100,6$), for the SyC̅ case are ($25,12,10,{10}^{-4},6$), and for the $\overline{2-\mathrm{SyC}}$ case are ($40,10,10,{10}^{-4},6$) (B) Period of the attracting limit cycle found by numerical simulation at varying ($w_{\mathrm{inh}},w_{\mathrm{ampa}}$) and fixed $w_{\mathrm{nmda}}=10$ nS in cases (i)–(ii) and at varying ($w_{\mathrm{inh}},w_{\mathrm{nmda}}$) and fixed $w_{\mathrm{ampa}}=12$ nS in cases (iii), (iv). Initiation parameters for cases (i)–(iii) are $\mathrm{\Delta }=50$ and $d=6$, while for cases (ii)–(iv) are $\mathrm{\Delta }={10}^{-4}$ and $d=6$
