Figure 2.

Left schematic of the 16-cell cluster in Drosophila. Here, the gray cell of the network denotes the oocyte, whereas blue cells denote cells directly connected to the oocyte, red cells lie two connections away, green cells are 3, and, finally, yellow cells are 4. Right For a series of initial conditions for $\left(X_i,Y_i\right),i>1$ selected from the distribution $U\left(\mathrm{0,1}\right)+1.25$, using the systems of Eqs. 1, 2, 3, and 4 reveals oscillations within the network based on distance from the oocyte, similar to previous experimental observations for $\delta =0.06$ (17).
