Genetics, physiology and anatomy of olfaction is widely studied in Mus musculus . 

With the notable exception of body-borne odors, however, only few studies have so far assessed olfactory performance in the mouse at the organismal level.

With regard to olfactory sensitivity of Mus musculus, detection thresholds for little more than a dozen substances have been reported. This is surprising given the importance of basic data on olfactory sensitivity for the choice of adequate stimulus concentrations in electrophysiological or functional imaging studies and the frequent use of sets of structurally related odorants for elucidating possible correlations between molecular structural features and measures of physiological activity or discrimination performance
