Figure 4

Spatio-temporal surface plots showing the behavior of four different circuits at later times, and on the right the corresponding circuits. Surface plots (panel a, c, e and g) represent the main types of patterns observed: a) Stable pattern with reminiscent pattern (Group I). c) stable pattern with a large hb suppressing all genes except gt (Group II). e) Oscillatory pattern where all genes except Tll oscillate (Group III). g) An oscillatory pattern where all genes except Kr and kni oscillate at the posterior (Group IV). In panel h the reduced circuit is shown. Only the connections that correlate with this particular pattern are shown. In this circuit typical oscillatory motifs can be recognized. Edges between two vertices indicate activation (green) or repression (red). The edge thickness is proportional to the absolute weight of the interaction.
