Web16 de dez. de 2024 · A general FitzHugh–Rinzel model, able to describe several neuronal phenomena, is considered. Linear stability and Hopf bifurcations are investigated by means of the spectral equation for the ternary autonomous dynamical system and the analysis is driven by both an admissible critical point and a parameter which … Web14 de jul. de 2012 · 4. Bifurcations • A bifurcation is a qualitative change in the phase portrait of a system of ODE's. A static bifurcation: Eigenvalues are. 5. Supercritical Hopf Bifurcations They occur when the real part of a complex conjugate pair of eigenvalues moves through zero. 6.

Web12 de abr. de 2024 · Continuous lines correspond to the bifurcations of the homogeneous manifold given by Eq (38) obtained with AUTO-07p: saddle-node on an invariant cycle (SNIC, dark blue), supercritical Hopf (HB+, continuous red), subcritical Hopf (HB-, dashed red), saddle-node (SN, brown), and homoclinic (Hom., purple). WebHopf bifurcation. Many studies have shown that these bifurcations are supercritical, but, by using simulations in a comoving frame of reference, we present numerical results which show that subcritical bifurcations are also present within FitzHugh-Nagumo. We show that a hysteresis region is present at the boundary of the rigidly
