Fig. 19

Periodic MMOs with signatures 16–18 of the Hodgkin–Huxley model (32) with \(\varepsilon =0.0083\) and \(I=9.74\), plotted together with their associated ribbons \(R_{6}\)–\(R_{8}\) of the extended attracting slow manifold. Panels (a)–(c) show the stable MMO 16 (black) and the unstable MMOs 17 and 18 (gray), respectively. The insets are enlargements near the line \(L^{a}_{2}\). Each ribbon \(R_{i}\) is bounded by its respective pair of twin canard orbits \(\xi _{i}\) and \(\xi '_{i}\)
