In their recent BBS article (doi.org/10.1017/S014...), Steve Fleming (@smfleming.bsky.social) and Matthias Michel (@matthiasmichel.bsky.social) discuss the slowness of conscious vision and the predictions generated by an internal model of the world. 1/2

Two great Team Days at the lab last week! 🧠✨ A great mix of scientific discussions, brainstorming, tutorials, and informal chats—fueling both collaboration and new ideas. On the menu: implicit timing, temporal distortions, time in working memory, and cognitive maps! #LabLife

📣New paper out! We successfully replicated our previous work (Azizi et al., 2023), demonstrating that alpha activity is a marker of contextual changes during resting-state. w/ R. Bordas and @virginievanw.bsky.social shorturl.at/bKAFp

Spontaneous Oscillatory Activity in Episodic Timing: An EEG Replication Study and Its Limitations
Episodic timing refers to the one-shot, automatic encoding of temporal information in the brain, in the absence of attention to time. A previous magnetoencephalography (MEG) study showed that the rela...

Preprint out, from my work with @mamassian.bsky.social and Anne! We show that time perception is shaped not only by context but also by structural constraints, by extending classical Bayesian models by explicitly quantifying a structural prior impacting duration discrimination. shorturl.at/q8bE6

Modeling how contextual and structural biases shape duration perception
Human time perception is flexible and shaped by both structural constraints and contextual influences. Disentangling these sources of bias is essential for understanding the predictive mechanisms unde...

🚀New paper out! With @lauradugue.bsky.social & @kirstenpetras.bsky.social, we show that traveling waves seen in EEG/MEG sensors might reflect real waves on the brain’s visual cortices—not just artifacts. Based on a MEG-EEG dataset with visually triggered traveling waves. tinyurl.com/st4bkday
