Transition from synchrony to swimming. Plot of dINs’ voltage recordings at varying time shows synchronous activity before the dynamics are locked into synchronous (A) and double-synchronous regimes (B) before then converging to the swimming mode. In both (A) and (B) initiation parameters are set to \(\Delta=0\), \(d=6\) and \(A=0.04\). At time \(t^{*} =0.3\) s the system is integrated starting from a perturbed initial point. This point is obtained by adding a normally distributed vector of numbers with equal variance \(\sigma=10^{-3}\) to each variable at time \(t^{*}\). Values of synaptic strengths are \(w_{\mathrm{ampa}} =10\), \(w_{\mathrm{nmda}} =10\), \(w_{\mathrm{inh}} =22.2\) in case (A) and \(w_{\mathrm{inh}} =60\) in case (B)
