From an initial 106 parameter sets, the number of mono-, bi-, and tristable sets was determined (285 parameter sets were omitted; see Computational Approach Details for details). “Polarizable (stimulus required)” refers to parameter sets that require a sufficiently large perturbation from an HSS to polarize. “Polarizable (linearly unstable)” refers to those parameter sets that are LPA unstable (LPA Screen) or those parameter sets that are unstable with respect to noise around one or more HSSs in the PDE Screen. “Not Polarizable” refers to parameter sets that did not polarize using our numerical parameters and initial conditions.
