Behavioral responses to muscone in MOR215-1 KO mice. A, Time to find the odor source in WT C57BL/6 mice (W) and MOR215-1 KO mice (K). Each triangle depicts a single individual. Animals that failed to find muscone (left) or eugenol (right) in 5 min were plotted at 5. PG, Propylene glycol. Muscone and eugenol were serially diluted from 10−1 (10%) to 10−7 (0.00001%) in PG and from 10−1 (10%) to 10−8 (0.000001%) in mineral oil. B, Summary of odor source-exploring experiments shown in Figure 5A. Vertical axis represents the percentage of the animals that found the odor sources within 5 min. The number of animals that found the odor sources and the number of total animals examined are shown inside each bar.
