Method "[Researchers] built a microscope which automatically follows individual cells." See link
Comments "The motion appears as an alternating sequence of intervals during which changes in direction are gradual or abrupt-[researchers] call these “runs” and “twiddles”, respectively. Genetic and environmental differences in behavior are associated chiefly with the lengths of runs. Fig. 1 illustrates this for the wild type and a nonchemotactic mutant. A number of results of a quantitative run-twiddle analysis are given in Table 1." See notes beneath table
