Figure 3. Chronotaxic system.

(a) Time-dependent point attractor x^A(t), whose trajectory is shown as a thick line, is the main characteristic of a chronotaxic system. Trajectories with different initial conditions (red dots) are approaching x^A(t). (b) The simplest configuration of dynamical system where a response system x may be chronotaxic due to a drive system p. Detailed definition of chronotaxic systems is given in Methods.
