The nematode Caenorhabditis elegans (C. elegans), a relatively simple organism in structure, is one of the most well-studied multicellular organisms. We developed 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 circuit model based on the actual nematode. The model uses neural oscillators to generate rhythmic movement. Computer simulation confirmed that the virtual C. elegans realizes motor control similar qualitatively to that of the actual organism. Specified classes of neurons are killed in the neural circuit model corresponding to actual unc mutants, demonstrating that resulting movement of the virtual C. elegans resembles that of actual mutants.
