Abstract
This work concerns the long-term dynamics of a spatiotemporal many-body deterministic model that exhibits emergence and self-organization, and which has been recently proposed as a new paradigm for Artificial Life. Collective structures emerge in the form of dynamic networks, created by bursts of spatiotemporal activity (avalanches) at the edge of a synchronization phase transition. The spatiotemporal dynamics is portraited by a motion picture and quantified by time varying collective parameters, which revealed that the dynamic networks undergo a "life cycle", made of self-creation, self-regulation, and self-destruction. The power spectra of the collective parameters show 1/f power-law tails, and the statistical properties of the avalanches, evaluated in terms of their size and durations, show power laws with characteristic exponents in agreement with those values found in the literature concerning neural networks. The mechanism underlying avalanches is discussed in terms of local-to-collective excitability. Finally, the connections that link the present work to self-organized criticality, neural networks and artificial life are discussed.
