What is the minimal exposure required to process facial features? In our reply to Mamassian & Wexler in Nat Comm, we address important questions about the limits of this approach and explain why manipulating exposure duration can offer advantages over other common visibility manipulations.

Open postdoc position👈 We have an open position, starting early 2026, to work on an exciting project aiming at better understanding the role of thalamo-cortical brain oscillations in perception with a comparative, cross-species (animal-human) component based on electrophysiology (incl. scalp EEG).

🚨New preprint from the Dugué Lab! Happy to share our last work on #attention_rhythms, co-led by @cogsenoussi.bsky.social & former Dugué Lab PhD student @lauriegalas.bsky.social, and in collab with Niko Busch 🎉 @upcite.bsky.social | @erc.europa.eu | #neuroskyence www.biorxiv.org/content/10.1...

Theta-rhythmic attentional exploration of space

Attention facilitates stimulus processing by selecting specific locations (spatial attention) or features (feature-based attention). It can be sustained on a given location or feature, or re-oriented ...

We put out this preprint a couple months ago, but I really wanted to replicate our findings before we went to publication. At first, what we found was very confusing! But when we dug in, it revealed a fascinating neural strategy for how we switch between tasks doi.org/10.1101/2024.09.29.615736 🧵

Convergent neural dynamical systems for task control in artificial networks and human brains

The ability to switch between tasks is a core component of human intelligence, yet a mechanistic understanding of this capacity has remained elusive. Long-standing debates over how task switching is i...

🎉New project 🎉 doi.org/10.1101/2024... How do we navigate between brain states when we switch tasks? Are dynamics driven by control, or passive decay of the prev task? We shed light on this classic debate by comparing high-d linear dynamical systems fit to EEGs and RNNs during task-switching 🌀

The study suggests a few metacognitive states correlate with rational behavioural adjustments; this might help steering behaviour towards optimality. @lucvermeylen.bsky.social @sebraem.bsky.social @kobedesender.bsky.social @gonzalezgarcia.bsky.social @mruz.bsky.social www.nature.com/articles/s44...

On déplore la mise sous tutelle des universités aux US, mais la situation en France est extrêmement inquiétante et pourtant personne (ou presque) n’en parle. Merci à @juliengossa.cpesr.fr de tirer la sonnette d’alarme.

A friend included this anti-acknowledgement section on her PhD thesis. She also added the proposition: “Systematic bullying and undermining of girls and women in STEM starts early on and is the reason why they do not stay in science and related fields.” Absurd we still need to go through this 🧪👩‍🔬

There have been people less than helpful in my journey here. I wanted to acknowledge those too, bc I know I am not unique in this experience. No thank you to the physics study assoc that made me sing songs about how women couldn't study physics without sleeping with the professor, the day I stepped into university life. No thank you to the 5th year physics student that decided to assign me a stripper name within the first minute of meeting me in the physics coffee corner in my first year. No thank you to the technician that was responsible for onboarding me on the use of the cluster in my third year who raised his eyebrows and asked me if that meant I was some sort of computer girl. No thank you to the senior researcher that sent me utterly inappropriate texts after a conference, then proceeded to apologise months later by telling me they had not been meant for me anyway so no hard feelings remain hopefully And no thank you to him for attending every conference I've been to since. No thank you to the people who told me that it was surprising that I was doing a PhD since I was a girl. No thank you to the man who mistook me for a coffee lady at a conference, and after having to correct him two times that I did not work there, responded with you should consider it. No thank you to the researcher that asked me what I was wearing underneath my outfit during a conference. No thank you to the physicist who declared to a room full of other physicists that biologists don't know how to design an experiment. No thank you to the people who have called me scary instead of strong and intimidating instead of intelligent. And finally, no thank you to the exec board of the TU Delft, whose knee-jerk reaction to being held up a mirror about the social safety at the university, was to sue the party holding up the mirror instead of looking at the problems they highlighted. ... You have made me feel like I do not belong in science & I cannot forgive you for that.
