Social Preference Data for Experiments 1,2, and 4: Time spent in each chamber or investigating a holding cell with or without another mouse in it presented as mean ± SEM in sec. Significant differences between B6 groups and other groups from the same experiment and same column are represented as *(p<0.05).
