| Outline of Final Research Achievements |
(1) We proposed a mathematical model for cell movement in amoeba. We successfully reproduced the stimulation-induced differentiation of behavioral types, which was observed experimentally. These dynamics may be explained by a saddle structure around a canard solution. Our result imply that the differentiation of behavioral types in amoeba is modified step-by-step via the compounding of stimulation inputs.
(2) We proposed a continuous model for a pathfinding system. The proposed model autonomously finds a path connecting two specified vertices, and the path is represented by a stable solution of the proposed model. The system has a self-recovery property, i.e., the system can find a path when one of the connections in the existing path is suddenly terminated. Further, we demonstrate that the appropriate installation of inhibitory interaction improves the search time.
