Figure 5. Altered olfaction in Magel2-null mice.

A) Latency to find buried food tested in 10-week old mice. B) 24 week-old Magel2-null mice have increased latency to locate the food following a fast in the buried food olfaction test. C) Three way olfactory preference test. For both genotypes, the percent time spent with clean bedding is less than the percent time with soiled bedding (i.e. the sum of the percent time spent with female-soiled bedding and the percent time spent with male-soiled bedding). However, within the time spent with the two soiled bedding choices, control males prefer female-soiled bedding, while Magel2-null males spend an equivalent amount of time with the male-soiled bedding as they do with the female-soiled bedding. * p<0.05 (control vs. Magel2-null), error bars represent SEM.
