Experiment setup and timeline. (IMAGE) Eötvös Loránd University Caption (A) Photo of the rats with color-codes for individual identification and tracking. (C) Continuous tracking allowed for the reconstruction of each individual’s space use. The heatmap shows the space use of two rats during a 3-week period at the beginning of phase 3. Areas used only by a3 are shown with red, only by β1 with green, and areas visited by both (e.g. at the water and the feeder) are shown with yellow.
