Assessing reptation motion with the WormTracker — Matthias Weiß and •Carsten Schade — Experimental physics 1, University of Bayreuth

The locomotion pattern of C. elegans (a small transparent roundworm) is complex and depends on the properties of the environment. To gain a better understanding of the locomotion mechanism of C. elegans, it is mandatory to take a closer look on the motion of individual worms. To get the exact movement pattern of C. elegans in different environments, we have constructed a worm imaging platform. This platform monitors in a time-resolved fashion the accurate shape and center of mass of worms during their movement.The tracking station allows single- and multi worm tracking. In the single tracking mode it is possible to track a single worm for any period of time. Therefore it is possible to track the complete lifetime of a single worm. In the multi tracking mode, it is feasible to track all worms on the plate and therefore to get comparative data from the movements of a worm ensemble in the same environment. The tracking software and the hardware are programmed with Matlab and LabView, i.e. it is easy to develop additional software packages for customized measurements.
