嗅觉是许多物种,特别是夜间和黄昏哺乳动物,收集有关环境信息的基本方式。嗅觉线索提供大范围距离的信息,允许从简单的物体检测和识别到跟踪踪迹和使用远处的气味羽流进行导航等行为。在这篇综述中,我们讨论了自然嗅觉环境的特点,并提供了一个简要的概述如何气味信息可以采样,并可能表示和处理的哺乳动物的嗅觉系统。最后,我们讨论了最近的行为方法,解决哺乳动物如何从环境中提取空间信息在三个不同的背景下:气味跟踪,气味羽跟踪,更一般的,嗅觉引导的导航。最近的技术发展已经看到了哺乳动物嗅觉的时空方面获得了显着的关注,我们讨论了迅速发展的范例和刺激控制技术,以及它们的局限性的有前途的方面。我们的结论是,虽然仍处于起步阶段,气味环境的研究提供了一个切入点,了解哺乳动物如何提取有关空间的信息的机制。
The sense of smell is an essential modality for many species, in particular nocturnal and crepuscular mammals, to gather information about their environment. Olfactory cues provide information over a large range of distances, allowing behaviours ranging from simple detection and recognition of objects, to tracking trails and navigating using odour plumes from afar. In this review, we discuss the features of the natural olfactory environment and provide a brief overview of how odour information can be sampled and might be represented and processed by the mammalian olfactory system. Finally, we discuss recent behavioural approaches that address how mammals extract spatial information from the environment in three different contexts: odour trail tracking, odour plume tracking and, more general, olfactory-guided navigation. Recent technological developments have seen the spatiotemporal aspect of mammalian olfaction gain significant attention, and we discuss both the promising aspects of rapidly developing paradigms and stimulus control technologies as well as their limitations. We conclude that, while still in its beginnings, research on the odour environment offers an entry point into understanding the mechanisms how mammals extract information about space.
