Abstract
The structure of spiral waves is investigated in super-excitable reaction-d iffusion systems where the local dynamics exhibits multilooped phase-space trajectories. It is shown that such systems support stable spiral waves wit h broken rotational symmetry and complex temporal dynamics. The main struct ural features of such waves, synchronization defect lines, are demonstrated to be similar to those of spiral waves in systems with complex-oscillatory dynamics.
