Forward locomotion
An integrated neuro-mechanical model of C. elegans forward locomotion
... Abstract. One of the most tractable organisms for the study of nervous systems is the nematode Caenorhabditis elegans, whose locomotion in particular has been the subject of a number of models. In this paper we ...
