Figure 12From: M-current induced Bogdanov–Takens bifurcation and switching of neuron excitability classOne-parameter bifurcation diagrams for RTM model (28), showing the change in the bifurcation structure as \(g_{M}\) is varied. (a) \(g_{M}< g_{M}^{*}\) (the value at the BT point); (b) \(g_{M}^{*}< g_{M}<\widehat{g}_{M}\); (c) \(g_{M}>\widehat{g}_{M}\) (the value at the CP point). Green/blue curves show stable/unstable equilibria. Pink curves show maxima/minima of periodic orbits. Codimension one bifurcation point labels are described in Table 1Back to article page
