Theories of Odor and Odor Measurement (Unknown Binding)
objective odor measurement has been developed in terms of a possible theory of olfaction. Starting from accepted ideas concerning the structure and composition of the nerve cell membrane and the composition of the mucus, possible mechanisms of olfaction are advanced. Any odor-carrying substance must make physical contact with the interior part of the nose. Whether the mucous membrane is "punctured" by the odoriferous substance, or absorption by the mucus produces a change in the state of polarization of the membrane and induces firing, is still open to experimental verification. The authors review current theories of olfaction and some physical models of the olfactory apparatus.
