Bifurcation diagram for an isolated Wilson–Cowan node in the \((P,Q)\) plane. Here HB denotes Hopf bifurcation and SN a saddle node of fixed-points bifurcation. At points a and c we find \(H'(0) < 0\) and at point b \(H'(0) > 0\). A breakdown of FC (loss of global synchrony) within a globally coupled network is predicted at points a and c
