🚨 Preprint alert! 🚨 How does the olfactory bulb transform overlapping sensory inputs into representations that are easier to distinguish? New study by Sina Tootoonian, Yikai Yang, @andreas-t-schaefer.bsky.social @crick.ac.uk and myself.‬ www.biorxiv.org/content/10.6... A short 🧵 below

Our work on the perception of intermittent odor stimuli out in @natcomms.nature.com! Led by @luxorboero.bsky.social & former grad student Hao Wu; key contributions from @btolooshams.bsky.social, @siddjakes.bsky.social, @paulmasset.bsky.social, @josephdzak.bsky.social, Farhad Pashakhanloo, Demba Ba.

Excited to see our paper describing a stereotyped receptor map for smell (led by @davidhbrann.bsky.social ) out in the world! See below for short thread with open access link to paper www.nytimes.com/2026/04/29/s...

When it comes to sensory processing, cortex should not get all the credit... In olfaction, a key challenge is identifying odors regardless of concentration. Our new paper in @natneuro.nature.com shows how the olfactory bulb performs this crucial computation before signals even reach the cortex.

Academic friends, It's beyond heartbreaking to watch what's unfolding in Iran & the region. A few of us drafted an open letter calling for protection of civilians & of educational, research, medical & cultural institutions. Please read & sign if you agree: sites.google.com/view/protect... #IranWar

Looking for a postdoc to understand dynamic vision in action in freely moving mice? Get in touch! This is a @erc.europa.eu postdoc in a project between us and @sinzlab.bsky.social: miniature 2-photon, rich behavior tracking, and deep learning models linking natural behavior to cortical activity|RT

Out today in Nature: We uncover a neural mechanism for the integration of two internal states - hunger and estrous state - and how this integration shapes pup-directed behaviors in mice. www.nature.com/articles/s41...

Thrilled to share this work, long time in the making! Carried through creatively by @siddjakes.bsky.social after initial design & piloting by @trackingskills.bsky.social, with help from @trackingactions.bsky.social. Modeling in collaboration with Massimo Vergassola & Nicola Rigolli.

Animals’ sniffing drives rhythmic input to the olfactory system. How does this timing contribute to perception, especially beyond first steps of olfactory processing? We tested this using simple closed-loop optogenetics in our new paper: www.cell.com/iscience/ful...

Fun collaborative work together with the amazing lab of @sophiesteculorum.bsky.social now published!

🚨 Preprint alert! 🚨 Can mice estimate the distance to an odour source? New work led by Cristina Marin and colleagues, jointly supervised by @andreas-t-schaefer.bsky.social at the @crick.ac.uk and myself. Spoiler alert: Yes, they can! Read the paper here: bit.ly/43A9tF9 Short 🧵 below

My PhD project is out as a preprint! We combined 2P and synchrotron X-ray to understand mouse olfactory bulb circuits, linking physiology to structure in 3 animals! doi.org/10.1101/2025... 🙌 @carlesbosch.bsky.social, @apacureanu.bsky.social, @andreas-t-schaefer.bsky.social, @esrf.fr, @crick.ac.uk

Now in its final form, our recent work on how olfactory transduction currents help ensure sparse sensory coding. Led by a post-bac Kai Clane Belonio and a graduate student, Eyerusalem Haile, this was a group effort by the entire laboratory. www.jneurosci.org/content/45/1...

Olfactory neuroscientists have known for a while that their stimuli stink. A new analysis illuminates the extent of the problem. By @callimcflurry.bsky.social #neuroskyence www.thetransmitter.org/olfaction/sm...

Excited to share the sequel to our 2022 paper! In this follow-up, we show that the stable head direction (HD) signals we reported in blind mice rely on stereo olfaction—that is, the comparison of odor info. between the two nostrils. Link: www.nature.com/articles/s41... 🧵highlights below

Tomorrow morning, March 29th at 11:30 am, check out Symposium 31 at #NWG2025 @neurowissg.bsky.social organized by MODOLFOR member Tobias Ackels @tobiasackels.bsky.social

Meet our IMPRS faculty members at the German Neuroscience Society Meeting in Göttingen this week!

Check out our review comparing typical experimental to naturally-occurring odor concentrations. You might be surprised. www.jneurosci.org/content/45/1... Thanks to Matt and Betty for asking me to take part!

I am deeply grateful for this award, which not only recognizes my work but also reflects the invaluable contributions of my team, mentors, and supporters! It inspires me to continue working with my lab to deepen our understanding of how we perceive and interpret our environment.

Have you ever wondered how memories are processed downstream of the #hippocampus and how this is affected by #Alzheimer's? We believe we may find some answers by riding all the way down the fornix to the mammillary body. Apply here for a fully-funded #PhD with us: ovgu.b-ite.careers/56yvk

Sniffing helps animals identify smells and connect them to places and events, but noses can’t sense time or place. How do brains connect odors with internal models of the world? Our preprint suggests that the olfactory bulb participates in this connection. www.biorxiv.org/content/10.1...

Check out our new review in PLoS Biology on how dynamic odour information can help mammals to navigate through their environment. Led by the fantastic Anantu Sunil & Olivia Pedroncini, this also marks my first last author publication from the University of Bonn! journals.plos.org/plosbiology/...
