Tube-opening behaviour test under aversive conditions. (A) Schematic diagram of this test. Half of the home cage contains wet bedding and the other half contains dry, normal bedding. Tube containing the cagemate mouse on the wet bedding. (B) Tube-opening behaviour test for cagemate under the aversive condition: time spent in the area. (C) Average speed of the test mouse in each bedding. (D) Comparison of the latency to lid-opening when the tube contains the cagemate is placed on wet or normal bedding. (E) Latency to lid-opening in various conditions of the tube-opening behaviour test. All data are presented as box plots. (E) Statistical significance is represented by top bars: *p < 0.05. The p values were calculated using paired t-test (B,C) and one-way repeated measures ANOVA (D,E). n = 9 animals per test.
