IV. MODEL
\ A prediction of the model is that algae can switch behavior successively from positive phototaxis, to backand-forth, to negative phototaxis before reverting back to positive phototaxis. Such is the case for three consecutive stimuli of I0 = 0.02 µmol · m−2 ·s −1 spaced by 90 s and a pause of 30 min before the fourth stimulus, see Fig. 8d.
\
This switch through all phototactic behaviors requires a precise tuning of both the light intensity and the waiting times, which is experimentally tedious. We were however able to experimentally observe the switch from positive to back-and-forth behavior and from back-and-forth to negative behavior, see Supp. Fig. 5.
