Synaptic weights and input strengths. Two different sets of synaptic weights \(g_{\mathrm {syn}}^{i j}\) and external input strengths \(i^{\mathrm {ext}}_{i}\) used in our simulations of system (1), with units (mS) omitted. Top: “standard” weights; bottom: “strong cross-excitation” weights. Solid lines ending in circles denote inhibitory connections; dashed lines ending in arrows represent excitatory ones. Both sets of weights include certain symmetries but the activity they support is robust to asymmetric perturbations
