Algorithms for olfactory search across species

KL Baker, M Dickinson, TM Findley… - Journal of …, 2018 - Soc Neuroscience
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 …

Distinct dopamine receptor pathways underlie the temporal sensitivity of associative learning

A Handler, TGW Graham, R Cohn, I Morantte… - Cell, 2019 - cell.com
Animals rely on the relative timing of events in their environment to form and update
predictive associations, but the molecular and circuit mechanisms for this temporal …

A neural network for wind-guided compass navigation

TS Okubo, P Patella, I D'Alessandro, RI Wilson - Neuron, 2020 - cell.com
Spatial maps in the brain are most accurate when they are linked to external sensory cues.
Here, we show that the compass in the Drosophila brain is linked to the direction of the wind …

A neural circuit for wind-guided olfactory navigation

AMM Matheson, AJ Lanz, AM Medina, AM Licata… - Nature …, 2022 - nature.com
To navigate towards a food source, animals frequently combine odor cues about source
identity with wind direction cues about source location. Where and how these two cues are …

Odour motion sensing enhances navigation of complex plumes

N Kadakia, M Demir, BT Michaelis, BD DeAngelis… - Nature, 2022 - nature.com
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 …

Flexible navigational computations in the Drosophila central complex

YE Fisher - Current opinion in neurobiology, 2022 - Elsevier
Insects can perform impressive feats of navigation, suggesting a sophisticated sense of
direction and an ability to choose appropriate trajectories toward ethological goals. The …

Drosophila olfaction: past, present and future

R Benton - Proceedings of the Royal Society B, 2022 - royalsocietypublishing.org
Among the many wonders of nature, the sense of smell of the fly Drosophila melanogaster
might seem, at first glance, of esoteric interest. Nevertheless, for over a century, the 'nose'of …

Walking Drosophila navigate complex plumes using stochastic decisions biased by the timing of odor encounters

M Demir, N Kadakia, HD Anderson, DA Clark… - Elife, 2020 - elifesciences.org
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 …
