From: Bifurcation analysis of a two-dimensional discrete Hindmarsh–Rose type model
(a) Bifurcation diagram of map (3) in \((\delta ,x)\) plane for \(a=2\), \(b=2\), \(c=1\), \(d=3.204\), the initial value is \((-2.14737621,1.16253284)\). (b) Maximum Lyapunov exponents corresponding to (a). (c) Bifurcation diagram of map (3) in \((\delta ,x)\) plane for \(a=2\), \(b=3\), \(c=0.8\), \(d=3.208\). The initial value is \((-2.14737621,1.16253284)\). (d) Maximum Lyapunov exponents corresponding to (c)
