(A) Timeline for Experiment 2, the shaded box indicates the data that are shown in this figure. (B) All groups of mice spent significantly more time sniffing male-soiled or pup-soiled bedding compared to clean bedding. Within a particular odor stimulus, there were no differences between groups. (C) There were no significant differences between groups in latency to sniff a particular stimulus. All mice were faster to sniff pup or male-soiled bedding compared to clean bedding. (D) All mice visited male and pup-soiled bedding cups more frequently than clean bedding cups. Data are expressed as Mean ± SE.
*Significantly different from male or pup-soiled bedding stimulus, p<0.0001
