Summary: A system of delay differential equations representing a simple model for a ring of neurons with time delayed connections between the neurons is studied. Conditions for the linear stability of fixed points of this system are represented in a parameter space consisting of the sum of the time delays between the elements and the product of the strengths of the connections between the elements. It is shown that both Hopf and steady state bifurcations may occur when a fixed point loses stability. Codimension two bifurcations are shown to exist and numerical simulations reveal the possibility of quasiperiodicity and multistability near such points.
