The orientational dynamics is temperature-dependent. A Two discrete and independent Markov chains describe the reorientation dynamics. The first one (top) selects the bout type, either turn (T) or forward (F), given the transition rate pturn, while the second one (bottom) determines if the fish is in the left (L) or right (R) state with a transition rate denoted pflip. B Mean ternarized reorientation Δ of the next bout, given the current bout reorientation. Shaded area is the sem, solid line is the fit (Eq. 1). C Temperature dependence of pflip. The dashed line at 0.5 indicates a memoryless process. D Schematic representing a motion sequence generated by the two discrete Markov chains. The hidden underlying orientational signal that sets the left/right state of the fish is exposed only when the fish performs a turning bout and can be estimated (dashed line) for each trajectory. E Trajectory-averaged autocorrelation function of Δ (RΔΔ) and associated fit (Eq. 2). F Temperature dependence of kflip, extracted from two methods: pflip divided by the mean interbout interval associated with each temperature (red, shaded area is the s.e.m.) and from the fit of the autocorrelation function (purple, error bar 95% confidence interval)
