A: 3-population model architecture. Populations 1 and 2 encode the rivalry percepts, while population 3 represents background activity. Third population receives a small background input I_bg to ensure it remains active when I₁ = I₂ = 0. Inhibition from population three prevents activity in u₁ and u₂ when I₁ = I₂ is low. This prevents the circuit from operating in the ID oscillation regime. Inhibition to the third population allows u₁ and u₂ to assume activity when I₁ = I₂ become sufficiently high. B: dynamical behavior of the model. In terms of general dynamical behavior, Figs. 9B and 10B are identical. We set β₁ = 2, β₂ = 4, δ = 1, and γ = 3. Firing-rate functions are f₁(x) = ${\sqrt{\left[x\right]}}_{*}$ with c = 0.05 and f₂(x) is a sigmoid with r = 1.5 (see appendix).
