Approach for detecting canard orbits in the Hodgkin–Huxley model (32) with \(\varepsilon =0.0083\) and \(I=9.74\). Panel (a) shows the integration time T versus the v-values \(v_{1}\) of the end points of orbit segments that satisfy (47); the black, gray and red dots correspond to a selection of the computed orbits segments. Panel (b) shows these selected orbit segments from panel (a) in their respective colors, in projection onto the (\(n,v\))-plane
