Simple behavioral assessment of mouse olfaction

Curr Protoc Neurosci. 2009 Jul;Chapter 8:Unit 8.24. doi: 10.1002/0471142301.ns0824s48.

Abstract

This unit presents two basic protocols that offer rapid assessments of anosmia (the absence of a sense of smell) in mice. The buried food test is used to check for the ability to smell volatile odors. The olfactory habituation/dishabituation test is used to test whether the animal can detect and differentiate different odors, including both nonsocial and social odors. A non-contact method of odor presentation, along with a general method for collecting urine samples, is given as an alternate protocol. The tests described in this unit only require simple equipment and can be adopted readily by most laboratories.
