Signal integration and adaptive sensory diversity tuning in Escherichia coli chemotaxis

JP Moore, K Kamino, R Kottou, TS Shimizu, T Emonet - Cell Systems, 2024 - cell.com
In uncertain environments, phenotypic diversity can be advantageous for survival. However,
as the environmental uncertainty decreases, the relative advantage of having diverse …

Sensing complementary temporal features of odor signals enhances navigation of diverse turbulent plumes

V Jayaram, N Kadakia, T Emonet - Elife, 2022 - elifesciences.org
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 …

Adaptive temporal processing of odor stimuli

SC Brandão, M Silies, C Martelli - Cell and Tissue Research, 2021 - Springer
The olfactory system translates chemical signals into neuronal signals that inform behavioral
decisions of the animal. Odors are cues for source identity, but if monitored long enough …

Temporal novelty detection and multiple timescale integration drive Drosophila orientation dynamics in temporally diverse olfactory environments

V Jayaram, A Sehdev, N Kadakia… - PLoS computational …, 2023 - journals.plos.org
To survive, insects must effectively navigate odor plumes to their source. In natural plumes,
turbulent winds break up smooth odor regions into disconnected patches, so navigators …

Modelling the mechanics of exploration in larval Drosophila

J Loveless, K Lagogiannis, B Webb - PLoS computational biology, 2019 - journals.plos.org
The Drosophila larva executes a stereotypical exploratory routine that appears to consist of
stochastic alternation between straight peristaltic crawling and reorientation events through …

Neural circuits for fast Poisson compressed sensing in the olfactory bulb

J Zavatone-Veth, P Masset, W Tong… - Advances in …, 2023 - proceedings.neurips.cc
Within a single sniff, the mammalian olfactory system can decode the identity and
concentration of odorants wafted on turbulent plumes of air. Yet, it must do so given access …

Odor response adaptation in Drosophila—a continuous individualization process

S Jafari, M Alenius - Cell and Tissue Research, 2021 - Springer
Olfactory perception is very individualized in humans and also in Drosophila. The process
that individualize olfaction is adaptation that across multiple time scales and mechanisms …

Bifurcation enhances temporal information encoding in the olfactory periphery

K Choi, W Rosenbluth, IR Graf, N Kadakia, T Emonet - bioRxiv, 2024 - biorxiv.org
Living systems continually respond to signals from the surrounding environment. Survival
requires that their responses adapt quickly and robustly to the changes in the environment …

Habituation as a neural algorithm for online odor discrimination

Y Shen, S Dasgupta… - Proceedings of the …, 2020 - National Acad Sciences
Habituation is a form of simple memory that suppresses neural activity in response to
repeated, neutral stimuli. This process is critical in helping organisms guide attention toward …

Optimal compressed sensing strategies for an array of nonlinear olfactory receptor neurons with and without spontaneous activity

S Qin, Q Li, C Tang, Y Tu - Proceedings of the National …, 2019 - National Acad Sciences
There are numerous different odorant molecules in nature but only a relatively small number
of olfactory receptor neurons (ORNs) in brains. This “compressed sensing” challenge is …
