Thrilled: my PhD work “Reconstructing voice identity from noninvasive auditory cortex recordings” is now in @elife.bsky.social DNNs model human temporal voice areas & can reconstruct speaker identity from fMRI. Ty to supervisors, co authors, CERIMED & participants elifesciences.org/articles/98047

Reconstructing voice identity from noninvasive auditory cortex recordings
A low-dimensional voice latent space derived from deep learning captures speaker-identity representations in the temporal voice areas and supports reconstruction of voices preserving identity information.

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. www.biorxiv.org/content/10.1...

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

Happy to announce my first postdoc preprint at @bathellierlab.bsky.social on offset responses in the auditory system! We found although these responses are found throughout the central auditory system, they provide richer information about elapsed sounds in the auditory cortex. tinyurl.com/3y2nvpr9

Sound offset responses become highly informative in the auditory cortex
The entire auditory system downstream of the cochlea features pronounced offset responses, which follow the termination of sounds. Because of their ubiquity, it is still an unsolved question whether o...

I'm pleased to announce the publication of my PhD works, a large annotated dataset of vocalizations by common marmosets. With over 800,000 recordings and 253 hours of data, this is the largest annotated dataset. Check it out and let me know what you think! www.nature.com/articles/s41...

It's finally out! Visual experience orthogonalizes visual cortical responses Training in a visual task changes V1 tuning curves in odd ways. This effect is explained by a simple convex transformation. It orthogonalizes the population, making it easier to decode. 10.1016/j.celrep.2025.115235

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.

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...
doi.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.

New modelling of how episodic memory can arise from spatial mapping, just out in Nature: www.nature.com/articles/s41...

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/...
science.org
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.
