在种类繁多的动物中，种内和种间的交流和识别依赖于嗅觉。嗅觉是一种古老的感觉方式，它基于神经组织和功能的原理，在整个动物圈中似乎非常相似。因此，决定嗅觉输入信息的嗅觉刺激的“原始”、嗅觉通路中不同水平形成的“分子图像”的类型以及嗅觉信息处理的细胞机制在无脊椎动物和脊椎动物中是相似的。蛾类中的雄性嗅觉子系统就是一个很好的例子，它专门检测和分析同种雌性性信息素化学信号的定性、定量和时间特征。这个嗅觉子系统可以被看作是，并在这里提出，作为一个模型，其中一般的嗅觉系统的组织和功能的共同原则被夸大，以满足化学通信系统的要求，这是至关重要的生殖成功。
Intraspecific and interspecific communication and recognition depend on olfaction in widely diverse species of animals. Olfaction, an ancient sensory modality, is based on principles of neural organization and function that appear to be remarkably similar throughout the zoosphere. Thus, the ''primitives'' of olfactory stimuli that determine the input information of olfaction, the kinds of ''molecular images'' formed at various levels in the olfactory pathway, and the cellular mechanisms that underlie olfactory information processing are comparable in invertebrates and vertebrates alike. A case in point is the male-specific olfactory subsystem in moths, which is specialized to detect and analyze the qualitative, quantitative, and temporal features of the conspecific females' sex-pheromonal chemical signal. This olfactory subsystem can be viewed, and is here presented, as a model in which common principles of organization and function of olfactory systems in general are exaggerated to serve the requirements of a chemical communication system that is crucial for reproductive success.
