Extended Data Fig. 3: Homing heading direction of the mouse as a function of the animal’s position at the start of the homing path.
a, Examples of homing paths from one mouse starting at two distinct locations on the arena (two black circles). The homing paths of light and dark trials are shown separately. The arena border is depicted as a gray dashed circle. b, Starting position of homing paths grouped based on whether the starting position was on the left or right side of the arena. We excluded starting positions that were more than 30 cm away from the arena center. Starting positions within a 2-cm-wide vertical band at the center of the arena were also excluded. c, Distribution of median homing heading direction for homing paths starting on the left or right side of the arena. Data are shown separately for light and dark trials. d, Median homing heading direction for each mouse for homing paths starting on the left or right side of the arena (N = 17 mice, two-sided Wilcoxon signed-rank test, light trials: P = 1.526 ×10−5, Dark trials: P = 3.052 ×10−5). Box plots show median (center line), first and third quartiles (box bounds), and 1.5 × interquartile range (whiskers). e, Difference in median homing direction for homing path starting on the left or right side of the arena. One data point per mouse. The data are shown separately for light and dark trials (N = 17 mice, two-sided Wilcoxon signed-rank test, P = 1.526 ×10−5). f, Vector field of the median homing direction of homing paths starting at different positions on the arena. Each arrow represents the median homing direction of homing paths starting at the location of the arrow. The data from all mice are included and shown separately for light and dark trials. ****P < 0.0001.
