GluN2B2A(CTD) mice are impaired in the long-term social recognition of a female conspecific. (A) In the 1-h retention session, the three groups of mice tested were able to remember the previously presented female and spent less time investigating the female in the retention session. (B) Although the GluN2A2B(CTD) and the wild-type mice spent significantly less time investigating the familiar female in the 24-h retention session, the GluN2B2A(CTD) mice were unable to form a long-term memory of the female conspecific and spent as much time exploring the female in the retention session as in the training session. (*) P < 0.05, (**) P ≤ 0.01, (***) P ≤ 0.001.
