Fig. 7. Sample trajectories of day 1 (blue) and day 5 (red) for rat 9 in Experiment 3. (A) Map of virtual environment with cylinders drawn to scale. Hit cylinders are encircled by light grey discs. Starting points appear towards the top of the figure. (B) Detail of day 1 trajectory, as boxed in A. Dots mark every 30th trace sample (every 1.4 s). (C) Detail of day 5 trajectory, as boxed in A. (D) Rat average position relative to closest cylinder on day 1. (E) Histogram of body orientations on day 1 as measured using the angular incremental encoder. (F) Rat average position relative to closest cylinder on day 5. (G) Histogram of body orientation on day 5. Note the dominant orientation to ESE on day 5 compared to the orientation peak to S in day 1. For details, see text.
