Investigation of olfactory system regulating the innate behavior in the domestic cat

我们这项研究的主要目的是阐明控制在家猫身上观察到的一种本能行为的嗅觉系统。当一只猫遇到其他猫留下的尿迹时，它会相当感兴趣地闻尿迹，然后表现出本能的固定动作模式；猫抬起头，保持嘴巴半开，带着欣喜若狂的表情几秒钟。本研究从分析和行为两个方面论证了跳蚤诱导信息素的化学性质，信息素纯化的关键步骤，以及嗅觉系统检测信息素的方法。

Our main purpose of this study is to elucidate olfactory systems regulating an instinctive behaviour called the flehmen response" observed in the domestic cat. When a cat encounters urine marks deposited by other cats, the cat sniffs the urine marks with considerable interest, and then shows an instinctively fixed action pattern; the cat raises the head and holds the mouth partially open with an enraptured" expression for a few seconds. This study demonstrated that chemical properties of flehmen inducing pheromones, key steps for purification of the pheromones, and olfactory systems detecting the pheromones by both analytical and behavior approaches.
