New preprint w/ @akalt.bsky.social, Juliane Schubert, Nathan Weisz, & @clarepress.bsky.social 🎉 Predictive-brain accounts treat "prediction error" as one signal. We find it's two jobs, in two dissociable systems. And one of them you can watch in the pupil, as people listen to a story. 🧵 (1/9)

🚨Preprint! “Bayesian surprise tracks the strength of perceptual insight” - Work with @lindedomingo.bsky.social & @gonzalezgarcia.bsky.social Ever wondered what factors influence the subjective experience of suddenly understanding a previously unclear input? Click below: doi.org/10.64898/202...

Yesterday at #ICON2025 I got to present our poster with #EttoreAmbrosini, @palencianoap.bsky.social, and @mruz.bsky.social on flexible task representations. I loved the chance to share our preliminary results and hear such thoughtful feedback!
👩💻 New preprint out (FIRST one of my PhD journey) with the incredible @lindedomingo.bsky.social @ortiztudela.bsky.social @gonzalezgarcia.bsky.social "From sudden perceptual learning to enduring engrams: A representational perspective" 🧠 doi.org/10.31234/osf...
🚨 There's an open postdoc position on sudden perceptual learning at the CIMCYC (University of Granada) - very nice people, excellent research environment, and Spanish lifestyle! Go check it out :)
🚨 We’re hiring a postdoc! Join the FLARE project @cimcyc.bsky.social to study sudden perceptual learning using fMRI, RSA, and DNNs. 🧠 2 years, fully funded, flexible start More info 👉 gonzalezgarcia.github.io/postdoc/ DMs or emails welcome! Please share!
Very excited to share our new preprint on visual ambiguity resolution. Check it out 👇
New preprint! 🚨→ Determinants of Visual Ambiguity Resolution. A new work with @ortiztudela.bsky.social @jvoeller.bsky.social @martinhebart.bsky.social and @gonzalezgarcia.bsky.social We created ~2k images and collected ~100k responses to study visual ambiguity. www.biorxiv.org/content/10.1...

Novel Verbal Instructions Recruit Abstract Neural Patterns of Time-Variable Information Dimensionality
Human performance is endowed by neural representations of information that is relevant for behavior, some of which are also activated in a preparatory fashion to optimize later execution. Most studies...

📣 ICON Symposium Really excited to announce our symposium at @ICON this year on Sudden Learning Across Systems! Together with lots of cool people: @gonzalezgarcia.bsky.social @lindedomingo.bsky.social @ortiztudela.bsky.social @anikaloewe.bsky.social @jazzmaniatico.bsky.social and Andrea Greve!
This is work together with @jvoeller.bsky.social, @vincentcheung.bsky.social, @numole.bsky.social, Konstantin Weise, Markus Kiefer and @gesahartwigsen.bsky.social at @unileipzig.bsky.social and @copla.bsky.social @mpicbs.bsky.social.
🚨 New preprint!! Using condition-and-perturb TMS, we show that functional interaction between multimodal and modality-specific cortices is causally relevant for conceptual knowledge retrieval: ssrn.com/abstract=510...
Left Inferior Parietal Lobe and Auditory Cortex Jointly Contribute to Sound Knowledge Retrieval
BackgroundConceptual knowledge is central to human cognition. Neuroimaging studies suggest that conceptual processing relies on the joint contribution of modali
