Query: Spontaneous sarcomere dynamics   Sarcomeres are the basic force generating units of striated muscles and
consist of an interdigitating arrangement of actin and myosin filaments. While
muscle contraction is usually triggered by neural signals, which eventually set
myosin motors into motion, isolated sarcomeres can oscillate spontaneously
between a contracted and a relaxed state. We analyze a model for sarcomere
dynamics, which is based on a force-dependent detachment rate of myosin from
actin. Our numerical bifurcation analysis of the spontaneous sarcomere dynamics
reveals notably Hopf bifurcations, canard explosions, and gluing bifurcations.
We discuss possible implications for experiments.
