Building upon understanding he gained from research in neuroscience (the inhibition of inhibition principle), Ben-Jacob and his collaborators discovered that the ingenious scheme is composed of a stochastic switch regulated by a timer with adaptable clock rate (that is adjusted by the cell stress) via a special decision-circuit composed of a cascade of inhibitions. The decision-circuits of the individual bacteria are coupled by exchange of chemical messages between the cells to guarantee collective decision for the group benefit.
