title: [Splitting of the back edge of a propagating excitation pulse].
abstract: A new type of unstability of action potential propagating in spatially inhomogeneous electrically excitable media is announced. Numerical experiments with the FitzHugh-Nagumo model show that if the medium contains a region where membrane slow, outward currents are partially depressed then the back front of action potential passing through such a region can split forming a "burning drop"-solitary standing wave of depolarisation with finite "life duration".
