Abstract: The main objective of this thesis is to explore the underlying mechanisms of the chemotaxis behaviors of C. elegans. In this thesis, several complex chemotaxis behaviors are taken into consideration. First, C. elegans is considered as a point and the chemotaxis behaviors are modeled by artificial DNN. Next, the biological models are constructed by directly extracting from the biological neural wire diagram. Based on these biological models, the chemotaxis behaviors with or without speed regulation are investigated. Then, the 3D undulatory locomotion behaviors of C. elegans are explored by using artificial DNNs, which successfully perform the behaviors of finding food and avoiding toxin. Further, the undulatory locomotion is investigated based on the biological neural wire diagram and muscular structure. The research in this thesis provides some new methods to investigate the essence of locomotion of low level animals, and these models could serve as a prototype for other footless animals.
