Extended Data Fig. 3: Running behavior and representational drift measurements for flat, variable, and spatial odor tasks, and odor concentration measurements for variable odor task.

a-f) The average speed and lick profiles of each mouse versus track position across days in flat odor (a), variable odor (c), and spatial odor (e) tasks and their mean (b, d, and f). g) Photoionization detector (PID) measurements acquired from the olfactometer nose cone for the five-day protocol of the variable odor task described in Fig. 3c. Day 1 of the variable odor protocol is the same as the flat odor protocol in Fig. 3b. The measurements were performed while a mouse was running on a treadmill in a virtual environment. In the inter-trial-interval, after the mouse completed one lap and before the start of the next, the odor concentration was set to 0. h) Representational drift of various odor mouse groups measured by various measurements. The shaded region shows SEM. The three groups have little or no statistical difference by non-directional multiple repeated measures ANOVA comparisons (see Supplementary Information Table 1 for all comparisons).
