In this paper, systems formed by networks of simple nonlinear cells are stu
died. Using lattice models, some of the fundamental features of complex sys
tems such as self-organization and pattern formation are illustrated. In th
e first part of this work, a lattice of identical Chua's circuit is used to
experimentally study its global spatiotemporal dynamics, according to the
variation of some macroparameters, like the coupling coefficient or the nei
ghboring dimension. The second part of the paper deals with the remarkable
improvements regarding regularization and pattern formation, obtained in ne
tworks of nonlinear systems by introducing some spatial diversity, especial
ly generated by deterministic, unpredictable dynamics. Simulation results s
how that synchronixation and self-organization occur in networks with a few
nonlocally connected cells, with irregular topology and small spatial dive
rsity.
