Figure 15. Transformation stages of the phase lag maps for the pyloric circuit motif.

Here, a single connection decreases from , and through to in (A)–(D), respectively. Going from (A) to (B), a triplet of saddle-node bifurcations eliminate first the clockwise FP, and then subsequently the green FP at in (B) to (C). The growing domain of the dominant blue FP at widens further from (C) to (D) after the stable counter-clockwise, , FP is annihilated through the final saddle-node bifurcation.
