Odor mixtures can be perceived as configural (i.e., different from their components) or elemental (i.e., similar to their components). Previous work demonstrates that these perceptual modes are determined by both peripheral and central interactions among mixture components. Flavor consumption is associated with unique peripheral and central odor processing mechanisms, but how this context affects perception of odor mixtures remains unknown. Here, we used a flavor consumption task in rats to measure preferences for solutions of binary odor mixtures and their components. In contrast to previous findings using identical mixtures in other contexts, our results demonstrate that rats employ elemental mixture processing strategies in the context of consumption. We discuss potential peripheral and central mechanisms that could explain unique mixture perception during consumption. (PsycInfo Database Record (c) 2022 APA, all rights reserved).
