Thresholds of the dog for detection of inhaled eugenol and benzaldehyde determined by electroencephalographic and behavioral olfactometry.
Electroencephalographic olfactometry and behavioral olfactometry were developed to evaluate objectively the olfactory function of 12 dogs. These techniques were used to determined normative thresholds for benzaldehyde, a mixed olfactory and trigeminal stimulant, and eugenol, a suspected pure olfactory stimulant, in 12 dogs. Both techniques were effective in obtaining a mean threshold for clinically normal dogs. Electroencephalographic olfactometry was demonstrated to be more sensitive than was behavioral olfactometry. The techniques measured olfactory function by failure to evoke responses in dogs after ablation of olfactory mucosa. The contribution of trigeminal stimulation to the thresholds was not determined.
