Gosselin et al. observed that sound information is profoundly transformed from the ear to the central brain. This artwork by Wei Li (Institut de l’Audition, Paris) illustrates the complexity of processes underlying these transformations.

How are auditory features represented across the #AuditoryPathway? @bathellierlab.bsky.social show that #auditory feature tuning emerges through a mix of gradual & stepwise changes, with early representation of simple features & later refinement of complex ones @plosbiology.org 🧪 plos.io/4oi0XCY

Latest published paper of the lab, detailing the evolution of the auditory feature codes across the auditory system and identifies it to representational decorrelation process described in various sensory systems.

If you have missed it, wonderful workshop in Montpellier on most recent optical imaging techniques for neurosciences. One week left to register lnkd.in/etEmGyMm

Free registration, accomodation possible on site.

Two postdoc positions in the lab within the ERC Synergy project "Chronology" in collaboration with S. Ostojic, M. Jazayeri and V. van Wassenhove @virginievanw.bsky.social . Two focuses: sound sequences representations across the brain & novel all-optical technology. Contact: brice.bathellier@cnrs.fr

The geometry of cortical sound processing in slow wave sleep https://www.biorxiv.org/content/10.1101/2025.06.13.658070v1

New study of the lab showing that sleep preserve sound representations geometry in the auditory cortex but intermittently blocks the transfer of sensory information, possibly to provide both opportunities for surveillance and offline processing.

A nice new study of the lab showing that the auditory maintains a much more detailed short-term memory of the sound in the offset responses than subcortical regions of the auditory system. Next step would be to understand what are the neural dynamics underlying this.

The representation of mood in primate anterior insular cortex Understanding how the brain reflects and shapes mood requires resolving the disconnect between behavioral measures of mood that can only be made in humans (typically based on subjective reports of hap...

A putative neural correlate of mood!

One big (scandalous?) idea, simple analyses, and the STRONGEST brain/behavior correlation I've EVER seen (which is shocking, given that it's mood).

Work with: You-Ping Yang, @catrinahacker.bsky.social and Veit Stuphorn.

Feature-dependent decorrelation of sound representations across the auditory pathway Early studies on orientation selectivity in the visual cortex have suggested that sensory systems generate new feature representations at specific processing stages. Many observations challenge this v...

New preprint with systematic measurements of feature tuning in the mouse auditory system made with robust representation similarity analysis. Validates a range of earlier observations and generalizes beyond that.

Well I agree we made a wrong business plan on that one. Fees are there to make sure that people register and come. They just cover the buses and the food in fact.

Check the NeuroFrance conference. International travel grant available at IBRO ow.ly/AKTJ50UR2cr

#NeuroFrance2025 registration & abstract submission are open! 🥳
We'll be back in the beautiful city of Montpellier next May for the biggest neuroscience meeting in France. Don't miss out! 🤩

Elife has a new editor-in-chief. An opportunity to remember that Elife proposes a modern peer review system fostering transparency, fairness, and immediacy. Elife has contributed to move the entire system in these important directions, and hopefully will continue doing so.

In memoriam: Yves Frégnac, influential and visionary French neuroscientist Frégnac, who died on 18 October at the age of 73, built his career by meeting neuroscience’s complexity straight on.

Bahar Gholipour reflects on the legacy of Yves Frégnac, the French neuroscientist who built his career by meeting neuroscience’s complexity straight on.

Yes we lost Yves too early.

I hear that Yves Fregnac neuropsi.cnrs.fr/annuaire/yve... died. When I was a young PhD students, the earnestness of Yves was a major inspiration. Deep thoughts. Careful thinking. Big ideas. Best wishes to his family and friends.

📢 📢 📢 The deadlines for both registration and abstract submission have been extended for 1 week!

Do not miss this opportunity to participate in the Braincoder conference and shape the future of brain-machine interfacing!

The application deadline for the Sensation and Action conference 2025 is fast approaching! Join us for an exciting set of talks and for a chance to share your ideas: www.lakeconferences.org

Parallel mechanisms signal a hierarchy of sequence structure violations in the auditory cortex Responses to local and global violations in sound sequences are prediction errors and not simply the consequence of stimulus-specific adaptation.

Catching up from the dead time w/o X, here is the excellent recently published study by Sara Jamali with @standehaene.bsky.social using the local-global prediction paradigm in mice. Oddball signaling is not just adaptation. Sequence chunking responses in VIPs. And some more doi.org/10.7554/eLif...

We are still recruiting for PhD studentships in basic & translational brain sciences! SIDB provides an annual stipend of £25K, plus tuition fees (inc. international).

2️⃣ The second speaker in our highlight series is Guillaume Charvet, who has been involved in ground-breaking work developing brain-machine interfaces to transform the lives of patients with severe disabilities.

3️⃣ We are extremely excited to welcome Dmitry Rinberg to the Braincoder conference and hear about the fascinating work he and his team have been doing in using optogenetic stimulation to understand how the brain perceives information!

Dmitry's talk is titled: "Probing Perception with Optogenetics".

A spatial code for temporal information is necessary for efficient sensory learning The auditory system transforms temporal information in sounds into spatial information for rapid associations with decisions.

A milestone paper for the lab. First causal demonstration of the impact of temporal information format on learning & a clear demonstration that the mouse auditory system structures sound representations very similar to what sound categorization deep networks do. www.science.org/doi/10.1126/...

Two nice days of conference on brain machine interfaces, less than 20 days to register.
