k₁ and k₂ determines the self-organizing patterning. Square two-dimensional simulation with noisy initial conditions and linear modulations of the parameters k₁ and k₂ along the y- and x-axis, as shown in Fig. 3H. The two parameters increase linearly from 0 to 4 promoting transitions between lateral inhibition pattern, rotating waves, periodic wave patterns, homogeneous patterns and bi-stable frozen patterns.
