Fig. 7
Persistence time in the conditioned motility patterns of Amoeba proteus. a Trajectories of 15 amoebae under galvanotaxis, that previously acquired the systemic conditioned behavior after induction process, lost gradually the persistence towards the anode (times ranging from 27 to 44 min) and turned back to the cathode (white line). The colors of the trajectories represent the duration of the conditioned behavior, as is indicated in the top of the figure. b Histogram representing the durations of the conditioned behavior for the first, second, and third scenarios. The persistence times ranged between 20 and 95 min. The cells that lost the persistent conditioned behavior at the beginning of the tests were not represented. The three scenarios were shaded in different green tones for better comprehension
