Mentions: We explore these questions by modeling the C. elegans musculature as a viscoelastic rod with discrete rigid segments , and map the neuronal dynamics such that they activate the muscles and deform the rod (Fig. 1A). When motor neuron activity stimulates muscles , this activation is translated into force applied to the rod, which moves in accordance with the physical properties of C. elegans. By stimulating the command PLM neurons, we establish for the first time that motor neuron dynamics are indeed producing coherent oscillatory full body movements that resemble forward crawling (Fig. 1B, videos available here: http://faculty.washington.edu/shlizee/celegans/).
