定位刺激源是至关重要的。大多数生物体在不知道相关刺激来源的情况下无法进食、交配或逃跑。对于许多动物来说，嗅觉在搜索中起着至关重要的作用。虽然微生物的趋化性相对较好地理解，但在较大的动物中，嗅觉搜索的算法和机制仍然是神秘的。在这次研讨会上，我们将介绍我们在苍蝇和啮齿动物的嗅觉搜索的理解的最新进展。尽管它们的大小和行为不同，但这两个物种必须解决类似的问题，包括应对湍流气流的挑战，对环境进行采样以优化嗅觉信息，并将气味信息纳入更广泛的导航系统。
Localizing the sources of stimuli is essential. Most organisms cannot eat, mate, or escape without knowing where the relevant stimuli originate. For many, if not most, animals, olfaction plays an essential role in search. While microorganismal chemotaxis is relatively well understood, in larger animals the algorithms and mechanisms of olfactory search remain mysterious. In this symposium, we will present recent advances in our understanding of olfactory search in flies and rodents. Despite their different sizes and behaviors, both species must solve similar problems, including meeting the challenges of turbulent airflow, sampling the environment to optimize olfactory information, and incorporating odor information into broader navigational systems.
