Figure 2. Time spent in aggressive encounters for male GluN1.

^hypo(HYPO) and WT mice. In the social interaction task, male GluN1^hypo showed less aggressive behavior than WT mice. This was most apparent following habituation to the testing environment as a result of habituation leading to a large increase in aggressive behavior in the WT mice but not in the HYPO mice, with both groups showing very little aggressive behavior when not habituated to the testing context. Time spent in aggressive encounters is expressed as mean ± SEM.
