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).
气味混合物可以被感知为整体（即不同于其组成部分）或元素（即类似于其组成部分）。之前的工作表明，这些感知模式是由混合物成分的外围和中枢相互作用决定的。味觉的摄入与独特的外围和中枢气味处理机制有关，但这种情况如何影响对气味混合物的感知尚不清楚。在这里，我们使用大鼠的味觉摄入任务来测量对二元气味混合物及其成分溶液的偏好。与之前在其他情况下使用相同混合物的发现相反，我们的结果表明，大鼠在摄入时采用元素混合处理策略。我们讨论了可能的外围和中枢机制，可以解释摄入过程中独特的混合物感知。（PsycInfo 数据库记录（c）2022 APA，保留所有权利）。
