Trigeminally mediated odor aversions in starlings

Trigeminally mediated odor aversions in starlings

J R Mason et al. Brain Res. .

Abstract

Electrophysiological and psychophysical evidence has demonstrated that trigeminal receptors in the nasal cavity respond to odorants. Despite these demonstrations of trigeminal chemoreception, it is not clear whether naso-trigeminal stimulation can be used to mediate learned behaviors in contexts such as feeding. Here, we report that starlings will learn aversions to odorant volatiles in a feeding context and that these aversions can be mediated by trigeminal cues.
