Fluid turbulence is a double-edged sword for the navigation of macroscopic animals, such
as birds, insects, and rodents. On the one hand, turbulence enables pheromone …

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 …

Odour plumes in the wild are spatially complex and rapidly fluctuating structures carried by
turbulent airflows,,–. To successfully navigate plumes in search of food and mates, insects …

Odor attraction in walking Drosophila melanogaster is commonly used to relate neural
function to behavior, but the algorithms underlying attraction are unclear. Here, we develop …

How insects navigate complex odor plumes, where the location and timing of odor packets
are uncertain, remains unclear. Here we imaged complex odor plumes simultaneously with …

Highlights•Wind, location, size, and number of odor sources shape temporal odor
patterns.•Insects can detect fine-scale temporal odor patterns and integrate them over …

Using odors to find food and mates is one of the most ancient and highly conserved
behaviors. Arthropods from flies to moths to crabs use broadly similar strategies to navigate …

Human navigation relies on inputs to our paired eyes and ears. Although we also have two
nasal passages, there has been little empirical indication that internostril differences yield …

In most sensory modalities the underlying physical phenomena are well understood, and
stimulus properties can be precisely controlled. In olfaction, the situation is different. The …

We and others have shown that during odor plume navigation, walking Drosophila
melanogaster bias their motion upwind in response to both the frequency of their encounters …
