摘要
A spatially extended model of diffusively coupled (bio)chemical oscillators creates spatio-temporal disorder (hyperchaos) characterized by complex and weakly correlated concentration patterns in space and time. Applying different types of local stimulation we show that the system forms stable patterns with well-defined global order for certain windows of parameters. Spatio-temporal hyperchaos thus supports efficient pattern control with minimum effort. A possible relevance of this mechanism for experimentally observed calcium wave patterns is pointed out.
