Quantifying random walk properties of Caenorhabditis elegans with the WormTracker — •Carsten Schade and Matthias Weiss — Universität Bayreuth

The locomotion pattern of C. elegans (a small transparent roundworm)is complex and depends on the visco-elastic properties of the environment. Here, we have used a custom-made worm imaging platform to monitor the random walks of individual worms in varying environments. As a result, we have observed that the probability distribution of spatial increments depends on the visco-elastic properties of the worm's environment. Moreover, these probability distributions Show signatures of Levy-stable distributions, hence suggesting near-optimal search strategies to explore the environment.
