Impaired sense of smell and altered olfactory system in RAG-1(-∕-) immunodeficient mice.

Interestingly, however, RAG-1 −∕− mice showed an increase in the time spent exploring the social stimulus compared to unfamiliar ones (almond and banana) and showed a trend toward a normal pattern of habituation (although the differences between the 3 exposure were not significant) suggesting a preserved function of the vomeronasal organ and an impaired activity of the main olfactory system (see Discussion).
