Behavior change during recovery from starvation.

<p>A. Each point is a mean of fit dissimilarity over 14 worms recovering from starvation. The dissimilarities are between two 15 min cuts recorded from the same worm, and they are plotted against the time difference between the cuts. For instance, one of the points at averages the dissimilarity between the 15–30 min and the 45–60 min cuts of worm 1, the dissimilarity between the 15–30 min and the 45–60 min cuts of worm 2, …, and the dissimilarity between the 15–30 min and the 45–60 min cuts of worm 14. Other points at average dissimilarities between 30–45 min and 60–75 min cuts, between 45–60 min and 75–90 min cuts, …, and between 195–210 and 225–240 min cuts. Dissimilarities involving 0–15 min cuts are highlighted in red, e.g. the red point at averages dissimilarities between the 0–15 min and the 30–45 min cuts. The 0–15 min behavior was very different from behavior at all later times. Aside from this exception, a given worm’s behavior changed only gradually with time, as shown by the gradual increase in dissimilarity with time interval. B. Like A, except that state dissimilarity is plotted instead of fit dissimilarity. C. Individual worms behave differently from each other. As in A, each point is an average of fit dissimilarities between cuts separated by in time, but here each worm is compared not to itself, but to other worms. D. This plot shows mean ± standard error of between-worm dissimilarities plotted against time. The points of the fit dissimilarity plot are the same as those at in C, but now plotted against the time at which they were recorded. Both fit and state dissimilarities start out high, but decrease with time as the worms settle into their new behavior.
