Supplementary Movie 1 (fhn.mp4): Traveling Wave Evolution in the FitzHugh-Nagumo (FHN) Model Vincent Lovero (24727126) Stephanie Dodson (1933168) Timothy Lewis (21281402) Biological sciences Mathematical sciences cardiac dynamics action potentials dispersion curves fast waves slow waves This animation illustrates the parameter-dependent evolution of the traveling wave voltage profile (bottom left) and its corresponding linear stability spectrum (right) mapped to the FHN dispersion relation (top left). The current state is indicated by a blue marker on the dispersion curve. The pink square denotes a saddle-node bifurcation and green dot denotes a Hopf bifurcation. As the parameter varies, the fast wave transitions through the saddle-node bifurcation into a slow wave, shrinking slightly but maintaining a largely symmetric rise and fall that appears as a scaled-down version of the fast wave. Simultaneously, the spectrum panel visualizes the linear stability dynamics, showing the fast wave losing stability as a single complex-conjugate pair of eigenvalues crosses the imaginary axis during the Hopf bifurcation. 2026-10-02T12:04:10Z Dataset Media 10.60893/figshare.cha.33472045.v1 https://figshare.com/articles/media/Supplementary_Movie_1_fhn_mp4_Traveling_Wave_Evolution_in_the_FitzHugh-Nagumo_FHN_Model/33472045 CC BY 4.0
