The mechanism of generation of spiral wave patterns in populations of Dictyostelium was probed experimentally by external chemical perturbation. Results supported the hypothesis that wave pattern selection occured by slow temporal variation of cell excitability. The processes were studied by resetting the waves with a spatially uniform pulse of extrinsic cyclic adeninemonophosphate (AMP).
