Query: Bifurcations due to small time-lag in coupled excitable systems   A system of ODE's is used to approximate the dynamics of two delayed coupled
  FitzHugh-Nagumo excitable units, and study the relevant bifurcations. It is
shown that the Bautin bifurcation acts as the organizing center for the
dynamics of ODE's for small time-lags.
