This framework helps explain defect dynamics, spatiotemporal chaos, and spiral wave behaviors in excitable media. 4. Universal Dynamics and Defect Behaviors
How does a spherical embryo develop fingers? Alan Turing proposed the . He theorized that two interacting chemicals (a slowly diffusing activator and a rapidly diffusing inhibitor) could destabilize a homogeneous state to create stable, stationary concentration peaks. These chemical "pre-patterns" are thought to guide cell differentiation, resulting in features like leopard spots or shark teeth. pattern formation and dynamics in nonequilibrium systems pdf
In 1952, Alan Turing demonstrated that chemicals could interact and diffuse to spontaneously generate static spatial patterns. This requires: An chemical that stimulates its own production. An inhibitor chemical that suppresses the activator. This framework helps explain defect dynamics
