Parameters that define C. elegans locomotion. The silhouette of the animal is captured, and the centroid (indicated by small gray square) is determined. The centroids trace the trajectory of the animal, which consists of periods of forward motion punctuated by periods of backing up called reversals. The numbers indicate the sequence of the silhouettes, which do not represent evenly spaced time intervals in this diagram. Several of the parameters that we looked at are defined.
