Importance of gonadal status of the stimulus animals for social recognition. a Male test mice investigated novel and familiar GDX (open bars) or intact (striped bars) female stimulus mice in the social discrimination model. White bars represent the amount of time spent sniffing a novel conspecific contained in a wire corral during the 10 min sampling session. The grey and black bars represent the amount of time spent sniffing a novel mouse and a familiar mouse, respectively, during the 5 min choice session. b Chequered bars represent social memory scores.
