Happy to share our new preprint: Uncovering the representational geometry of durations Is time represented along a single mental timeline? We combine behaviour + EEG to show that duration is organised in a richer, multidimensional space. w/ @lnalborczyk.bsky.social & @virginievanw.bsky.social

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!

Everything you always wanted to know about intracranial correlates of #consciousness (but were afraid to ask): arxiv.org/abs/2510.08736 With @francoisstock.bsky.social, @liadmudrik.bsky.social, @meaperei.bsky.social and many great clinicians too busy for bsky! #iEEG

Neural correlates of perceptual consciousness from within: a narrative review of human intracranial research
Despite many years of research, the quest to identify neural correlates of perceptual consciousness (NCC) remains unresolved. One major obstacle lies in methodological limitations: most studies rely o...

Our #sEEG study is now published in Nature Communications: rdcu.be/eIkoG! 🧠 Key finding: We discovered neural evidence accumulation for visual perception that's independent of report preparation—recorded from >3000 channels across 3 experiments! #Neuroscience #Consciousness #OpenAccess

Cortical evidence accumulation for visual perception occurs irrespective of reports
Nature Communications - Perception can occur in the absence of report. Here, the authors use intracranial recordings to show that sequential sampling of sensory evidence in the ventral visual...

Check out our new multisensory decision study! We tackle a decades-old Q: does faster detection of bimodal targets come from a race or co-activation between modalities? And also a vital, orthogonal Q: is it one decision process or two? A1: co-activation A2: two! Read here: rdcu.be/eASYd

Distinct audio and visual accumulators co-activate motor preparation for multisensory detection

Are interoception and mental health linked? Many assume so, with interoception even described as a psychiatric “p-factor.” But in our latest preprint, we were surprised to find little evidence for such a connection. www.medrxiv.org/content/10.1... 🧵 Thread with our reflections on the matter 👇

Interoceptive Ability is Unrelated to Mental Health Symptoms: Evidence From a Large Scale Multi-Domain Psychophysical Investigation
Interoception-the sensing and perception of the internal viscera-is widely cast as a transdiagnostic mechanism linking brain-body interaction to mental illness. Prevailing models propose that altered ...

Our "I would have seen it if it were there" paper — a collaboration with @ranimo.bsky.social and @clarepress.bsky.social — is now out in Psych. Review. There’s a lot in this paper, but here are what I see as the 3 main takeaways: psycnet.apa.org/fulltext/202...
The title of the paper, "Beliefs about Perception Shape Perceptual Inference: An Ideal Observer Model of Detection", with the author names, and Fig. 1: a schematic of an inverse optics account of vision.

Through thick and thin, the ultra-resilient Ramla Msheik completed the main study of her PhD, which supports leaky evidence accumulation as a computational mechanism underlying perceptual confidence and subjective duration. Check it out! www.biorxiv.org/content/10.1...

Leaky evidence accumulation accounts for perceptual confidence and subjective duration

Hey Bluesky! I’m excited to share my new preprint with @matanmazor.bsky.social and @ruvidar.bsky.social, where we show that surface-level questionnaire filling behaviours drive correlations between mental health and metacognition (confidence ratings). osf.io/preprints/ps... [1/14]

Ever wondered how basketball players know when their throws are in/out? L. Brun & @perrineporte.bsky.social asked players to rate confidence in their throws under variable visual feedback. Turns out vision helps adjust confidence in successful, but not failed throws: papers.ssrn.com/sol3/papers....

The Role of Visual Feedback in Metacognitive Judgments of Motor Performance
Predicting the outcome of one’s actions is crucial for effective behaviour. The mechanical underpinnings of this metacognitive ability are, however, poorly unde
