A simulation model of the locomotion controllers for the nematode Caenorhabditis elegans

By J.A. Bryden and N. Cohen


This paper presents a simple yet biologicallygrounded\ud model of the C. elegans neural circuit\ud for forward locomotive control. The model considers\ud a limited subset of the C. elegans nervous\ud system, within a minimal two-dimensional environment.\ud Despite its reductionist approach, this\ud model is sufficiently rich to generate patterns of\ud undulations that are reminiscent of the biological\ud worm’s behaviour and qualitatively similar to\ud patterns which have been shown to generate locomotion\ud in a model of a richer physical environment.\ud Interestingly, and contrary to conventional\ud wisdom about neural circuits for motor control,\ud our results are consistent with the conjecture that\ud the worm may be relying on feedback from the\ud shape of its body to generate undulations that\ud propel it forward or backward
