Reactive Searching and Infotaxis in Odor Source Localization
Figure 5
Cognitive search trajectories obtained using infotaxis.
(A) Example it trajectories for no stimulation (green, left), minimum (dark green, middle) and medium (cyan, right) stimulation doses. The dots on the trajectories indicate pheromone detections. The black dashed line indicates the plume contour (see Methods). (B) Total number of turns in it trajectories for different stimulations. Identical conventions as in Fig. 3. (C) Track-angle histograms of it trajectories, different colors indicate different doses. (D) Total number of detections measured during reactive (sp, za, ze) and cognitive (it) searching using three stimulation doses and no stimulation. Identical conventions as in Fig. 3.
