Fig. 1.

After a 10-minute pre-test with a cotton tip apparatus in the home cage, mice were exposed to either 2.5 μl of water (H₂O, white, n = 12), vanilla (VNL, gray, n = 15), or the fox-derived predator odor, TMT (black, n = 13), for 10 min post-test. Displayed bars are mean and SEM of a duration (s) of contact with the apparatus/object, b time spent in the far corners, c defensive burying, and d Distance traveled (cm) in the home cage. e Representative heat maps of time and location of mice after H₂O, VNL, and TMT. The white triangle indicates the location of the stimulus. The legend indicates blue for minimum and red for maximum. *p < 0.05 vs. H₂O, ^^p < 0.01 vs VNL, #p < 0.05 vs. pre-test, ##p < 0.01 vs. pre-test
