Abstract：
:Previous research has shown that, in freely moving laboratory rats, the odors of benzyl alcohol, camphor, carvacrol, isopentenyl methyl sulfide, 2-propylthietane, salicylaldehyde, trimethylthiazoline, and xylene (plus other compounds) elicit high amplitude bursts of roughly 20-Hz waves (beta-waves) in the olfactory bulb and pyriform cortex. Since all these compounds are effective antifeedants in a variety of small herbivores, a more extensive test of the effect of the odor of a variety of antifeedants on pyriform cortex activity in meadow voles (Microtus pennsylvanicus) was undertaken. A beta-wave response was reliably elicited in the vole pyriform cortex by the odors of isopentenyl methyl sulfide (a component of fox odor), 2-propyl thietane (a component of stoat odor), and xylene but not by the odors of 29 other compounds. The results indicate: (a) that there are clear interspecific differences in the olfactory reactions of the pyriform cortex and (b) that not all antifeedants elicit beta-waves in the pyriform cortex.
