Response of bacteria to the imposition of a 1D square wave with 270 μm wide stripes. a The evolution of the speed profile normalised to its (time) average, with time increasing from red to violet (legend gives t in minutes): initially illumination is uniform, with the intensity getting increased from low to high at t = −7 min, then the pattern is applied at t = 0 for 15 min. b The spatial profiles of various normalised quantities as indicated in the legend after 15 min of patterned illumination. Error bars represent s.d. Dashed line (and grey area) is the average (±1 s.d.) over all tiles for the uniform case (t < 0). Error bars show propagated s.e.m.
