The study was carried out by numerical integration of a reaction-diffusion equation system. The feedback signal was derived from sensory domains with different geometries by introducing an algorithm. It was shown that the shape and size of the trajectories depend on the choice of the geometry of the sensory domain.Mahidol UniversityMathematicsPhysics and AstronomyArticleSCOPUS10.1103/PhysRevE.70.046221
