ABSTRACT This paper focuses on the nematode C. elegans which has a relatively simple structure, and is one of the most analyzed organisms among multicellular ones. We aim to develop a mathematical model of this organism to analyze control mechanisms with respect to locomotion. First, a new motor control model of the C. elegans is proposed, which includes both of the neuronal circuit model and the dynamic model of the body. Then, the effectiveness of the proposed model is verified through a series of computer simulations

    ABSTRACT: This paper explores the complex chemotaxis behaviors of C. elegans. These behaviors include finding food and avoiding toxin simultaneously under either dual-sensory mode or single-sensory mode as well as varying locomotion speed. In dual-sensory mode, the concentration difference between left side and right side is used to determine the orientation. In single-sensory mode, a memory neuron is involved to detect the concentration difference between two time steps for navigation. First, two models are explored, namely, dual-sensory model and single-sensory model. Then, an integrated model is proposed to perform all the chemotaxis behaviors synchronously. These three models are constructed biological by extracting the neural wire diagram from sensory neurons to motor neurons and can perform left turning, right turning, and speed regulation. The chemotaxis behaviors are characterized by a set of switching logic functions that decide orientation and speed. The wire diagrams are depicted as dynamic neural networks (DNN) and trained by the real time recurrent learning (RTRL) algorithm. By incorporating a speed regulation mechanism, C. elegans can stop spontaneously when approaching food or leaving toxin. Test results verify that the biological models can well mimic the chemotaxis behaviors of C. elegans.

    ABSTRACT: This paper focuses on the nematode , which has a relatively simple structure, and is one of the most analyzed organisms among multicellular ones. We aim to develop a computer model of this organism to analyze control mechanisms with respect to its movements. First, a neuronal circuit model for directional control and a kinematic model of the muscle body are proposed. Then, by integrating the two models, we construct the whole body model of . The effectiveness of the proposed model is verified through a series of computer simulations.

    ABSTRACT: The nematode Caenorhabditis elegans (C. elegans), a relatively simple organism in structure, is one of the most well-studied multicellular organisms. We devel-oped a virtual C. elegans based on the actual organism to analyze motor control. We propose a dynamic body model, including muscles, controlled by a neural cir-cuit model based on the actual nematode. The model uses neural oscillators to generate rhythmic move-ment. Computer simulation confirmed that the virtual C. elegans realizes motor control similar qualitatively to that of the actual organism. Specified classes of neu-rons are killed in the neural circuit model correspond-ing to actual unc mutants, demonstrating that result-ing movement of the virtual C. elegans resembles that of actual mutants.
