Superscripts *, ** and *** indicate t-test (uncorrected for multiple testing) p-values < 0.05, < 0.01 and < than 0.001, respectively. Independent sample t-tests were not performed for aggression counts and aggression duration.

Note - nonaggressive mice are defined as mice that did not perform any aggressive behavior acts defined in Table 7.
