在日常生活中很难闻到单分子气味，而嗅觉的日常功能主要依赖于处理环境中存在的复杂挥发物混合物（例如，来自食物或同类物质）。这样的处理允许对气味进行即时识别和分类，也允许对其他气味进行区分，以提取相关信息并有效地适应不同的环境。支撑这种对复杂气味混合物的高效分析的神经生理学机制正在开始被解开，并支持嗅觉，正如视觉和听觉一样，依赖于气味-物体编码的观点。这种气味混合物的结构处理，在我们的社会中有重要的应用（例如，调香师、调味师和酿酒师的艺术），直到最近几十年才得到科学的研究。这一过程取决于许多个体因素，其中包括发育阶段、生活方式、生理和情绪状态以及认知技能；这一过程在物种之间也表现出惊人的相似性。本综述收集了最近在动物、健康受试者和/或情感障碍患者中观察到的支持将复杂气味刺激视为气味物体的发现。它还讨论了外围到中央处理，以及认知和行为的意义。最后，本文强调了气味混合物的研究是研究日常嗅觉的一个原始窗口，并强调了对潜在生物过程的了解的必要性，这似乎对我们的表现和适应化学环境至关重要。
Smelling monomolecular odors hardly ever occurs in everyday life, and the daily functioning of the sense of smell relies primarily on the processing of complex mixtures of volatiles that are present in the environment (e.g., emanating from food or conspecifics). Such processing allows for the instantaneous recognition and categorization of smells and also for the discrimination of odors among others to extract relevant information and to adapt efficiently in different contexts. The neurophysiological mechanisms underpinning this highly efficient analysis of complex mixtures of odorants is beginning to be unraveled and support the idea that olfaction, as vision and audition, relies on odor-objects encoding. This configural processing of odor mixtures, which is empirically subject to important applications in our societies (e.g., the art of perfumers, flavorists, and wine makers), has been scientifically studied only during the last decades. This processing depends on many individual factors, among which are the developmental stage, lifestyle, physiological and mood state, and cognitive skills; this processing also presents striking similarities between species. The present review gathers the recent findings, as observed in animals, healthy subjects, and/or individuals with affective disorders, supporting the perception of complex odor stimuli as odor objects. It also discusses peripheral to central processing, and cognitive and behavioral significance. Finally, this review highlights that the study of odor mixtures is an original window allowing for the investigation of daily olfaction and emphasizes the need for knowledge about the underlying biological processes, which appear to be crucial for our representation and adaptation to the chemical environment.
