AON neurons can be excited by multiple dissimilar components within an effective mixture. A, In this example, four components of a single mixture (mixture7) induced significant subthreshold activity relative to mineral oil (data not shown). Conventions are as in Figure 1. B, Quantification of averaged net membrane potential change (subthreshold activity) induced by the entire mixture and its individual components during a 2 s odor presentation. *p < 0.05, ***p < 0.001, Student's t test versus mineral oil (vehicle only).
