The final preprint of my PhD is out! We present a neuro-computational approach that can approximate mental images and allows us to assess their qualities without introspection. We evaluated this approach on a large-scale EEG data set (43,200 trials). (1/n) www.biorxiv.org/content/10.6...

A neuro-computational approximation of the qualities of mental images
Mental images are challenging to study, given that our conscious experience is notoriously hard to access. The currently prevalent introspective methods are inherently subjective and can thus only pro...

How does the brain track an object even when it is occluded and in constrained, non-linear motion? 👁️🧠 In a new preprint, we use EEG+behavior to study how we mentally track motion (w/ @dkaiserlab.bsky.social, @luchunyeh.bsky.social, @kathadobs.bsky.social,...) www.biorxiv.org/content/10.6... 1/5 🧵

Cortical alpha rhythms predictively track occluded motion trajectories
Objects in the real world frequently move along complex, non-linear trajectories shaped by their environment. As they do, they often pass temporarily out of sight, occluded by the surrounding environm...

Come to my talk for some fun experiments combining drawings, DNNs and visual search! 👀🧠⛱️

What do we look for when searching for objects in our daily-life environments? Very happy that I can now share this review, together with @suryagayet.bsky.social , @predictivebrain.bsky.social and @peelen.bsky.social🥳 A brief thread below!

How segregated vs. integrated are face and body representations in human visual cortex? In this new preprint with @kathadobs.bsky.social, we use DNNs and fMRI to find out. www.biorxiv.org/content/10.6... #neuroskyence 🧵 1/n

New preprint! Why do people disagree about what looks beautiful, even when viewing the same stimulus? We show that shared aesthetic experience is linked to shared gaze during naturalistic viewing: www.biorxiv.org/content/10.6... 1/4

Check out our new preprint! 🎉 We demonstrate that real-world object search is shaped by both objects’ inherent variability and searchers’ individual priors, using a new approach that combines human drawings with DNN representational similarity analysis. ✍️🖥️👀

🧨 Preprint alert Is it easier to find a ball than a shoe? The answer lies in how variable we think these objects are in the real-world. www.biorxiv.org/content/10.6... w/ the amazing @dkaiserlab.bsky.social & @luchunyeh.bsky.social 🦄 🧵1/8

🚨 New preprints out!🚨 Excited to share two new preprints from my #MSCA project. With Daniel @dkaiserlab.bsky.social , Marius @peelen.bsky.social , and Belma Seferovic, we show how contextual associations shape real-world object representations and guide everyday visual task performance. 👇👇👇 1/n

I’m excited to share the first preprint from my PhD project! Together with Daniel Kaiser (@dkaiserlab.bsky.social), we investigated how internal models shape inter-individual differences in the perception and neural processing of natural scenes. Preprint: osf.io/preprints/ps... 1/n

New Correspondence with @davidpoeppel.bsky.social in Nat Rev Neurosci. www.nature.com/articles/s41... Here, we critique a recent paper by Rosas et al. We argue that "Bottom-up" and "Top-down" neuroscience have various meanings in the literature. PDF: rdcu.be/eSKYI

Investigating individual-specific topographic organization has traditionally been a resource-intensive and time-consuming process. But what if we could map visual cortex organization in thousands of brains? Here we offer the community with a toolbox that can do just that! tinyurl.com/deepretinotopy

Really interesting work by Bakhurin and colleagues challenging the reward prediction error hypothesis of dopamine: www.nature.com/articles/s41... I love this figure which both echoes and undermines the famous figure from Schultz et al. (1997).

How can we characterize the contents of our internal models of the world? We highlight participant-driven approaches, from drawings to descriptions, to study how we expect scenes to look! 🤩

It's very little we understand! There's the data gap but also very little done about the known and existing gaps
