Gas Chromatography Subject

Another approach to the operant evaluation of olfaction was taken by Stattelman and his colleagues (Stattelman et al. 1975). Here, the responsiveness of pigeons, chickens, and quail was examined. Subjects were placed in a chamber through which filtered air passed at a constant rate. Odorants were injected into the airstream with a gas syringe, and odorant concentrations in the airstream were evaluated by gas chromatography. Subjects were trained to peck at a bar in the presence of an odor. Concentrations were then reduced until pecking stopped. The lowest concentration that reliably elicited pecking was defined as threshold.
