Activator-Inhibitor Model

This clip demonstrates the activator-inhibitor model as presented by Alan Turing. While the video itself is very short, it shows the concept quite well. Relative to the reading, the blue color would represent the I compound, diffusing much more quickly away from the centers of diffusion and creating a negative feedback loop for the red color. The red/yellow centers represent the A compound, diffusing slowly and creating a positive feedback loop at the centers of diffusion.
