Mechanism of Interaction between Odorants at Olfactory Receptor Cells

Behaviorally relevant odors and tastes for most, if not all, organisms are mixtures of compounds, not single molecular species. Understanding chemosensory coding therefore requires understanding how multicomponent stimuli coactivate chemosensory pathways. The authors earlier reported that mixture su...

Description
Summary:Behaviorally relevant odors and tastes for most, if not all, organisms are mixtures of compounds, not single molecular species. Understanding chemosensory coding therefore requires understanding how multicomponent stimuli coactivate chemosensory pathways. The authors earlier reported that mixture suppression is the dominant type of interaction found in the antennular (olfactory) pathway of the spiny lobster, that it is due in part to odorants interacting at the receptor cells, and that mixture suppression in one type of taurine-sensitive receptor cell suggested that odorant molecules of different efficacies compete for common receptor sites. This study extends an initial observation by characterizing the dose-response function of single chemoreceptor cells in the antennule of the spiny lobster to three stimulatory odorants in the presence and absence of single doses of one to three suppressive odorants.
