Very happy to share that our INNERSPEECH project has been funded by the #ANR! We'll investigate the cognitive and neural bases of inner speech diversity and build a neurocomputational model of how it emerges during development. One PhD and one postdoc position will open soon; stay tuned!

A number simplex in the human medial temporal lobe

Humans handle numbers nimbly, suggesting a richer neural manifold structure than the prevalent mental number line model. In populations of medial temporal lobe (MTL) neurons in humans performing two s...

Open post-doc position in the study of perceptual fluctuations Position: post-doctoral (2 years) Locations: Paris, France (Ecole Normale Supérieure / CNRS) and Lausanne, Switzerland (University of Lausanne / CHUV) Deadline: September 4th, 2026 Start Date: Fall 2026 (with some flexibility) (1/8)

Complexity is ubiquitous in the world around us. But different stimuli are complex for different reasons. Does the mind nevertheless represent a ‘unified’ notion of complexity across domains? In @nathumbehav.nature.com, @chazfirestone.bsky.social & I show the answer is: yes! osf.io/preprints/ps...

Objects warp space in our mind, and events warp time in our mind. @samiyousif.bsky.social and I teamed up to review the work in these two literatures and suggest that there may be deep connections across them (with analogous influences of objects on space and events on time).

Sami Yousif@samiyousif.bsky.social · 5mo ago

(Perceptual) space and time are warped by the gravity of objects and events in their vicinity. There's been a flurry of work recently documenting examples of this gravity, all resulting in some really neat illusions. @brynnsherman.bsky.social and I discuss all of those, here: rdcu.be/e5SWo

Are you sure there’s no mosquito in the room? With @matanmazor.bsky.social, Chichi Dézier, @nfaivre.bsky.social & Louise Goupil, we study how we combine multiple sensory sources to be confident in presence and absence: While detection rely on one modality, confidence requires both channels to align!

If you analyse time-resolved data (M/EEG, iEEG, pupillometry, force recordings…) and feel limited by cluster-based permutation tests (CBPTs); especially when trying to determine when an effect starts or ends; you may want to try our new R package: lnalborczyk.github.io/neurogam/ #rstats #brms #EEG

Providing utility functions for fitting Bayesian generalised additive multilevel models (BGAMMs) to time-resolved data (e.g., M/EEG, pupillometry, mouse-tracking, etc) and identifying clusters.

Our review on intracranial research on consciousness is now out as a preprint: arxiv.org/abs/2510.08736. I believe that intracranial recordings provide one of the most exciting avenues for research on consciousness right now! If you agree, I think you will find the review interesting 🤓

Neural correlates of perceptual consciousness from within: a narrative review of human intracranial research

If you attend #TRF4 in Tokyo and always wondered how humans represent durations, make sure to check out @grassocamille.bsky.social’s talk on Sunday morning! Spoiler: Durations are mentally organised along (at least) three interpretable dimensions! More complex structure than we previously assumed.
