Abstract
The existence of a novel inwards propagating wave motion is demonstrated in a limit-cycle medium both for the FitzHugh-Nagumo and for modified Chernya k-Starobin-Cohen reaction-diffusion systems. The waves (pulses) are seen to be moving "backwards," that is, towards the point where the triggering pul se was initiated, instead of the regular propagation away from the origin. The feasibility of the phenomenon and some of its features are analyzed.
