We've posted a new fMRI study of semantic relations (has-part, is-a, made-of, etc.), a key aspect of language. We find that relations are represented in the same brain regions as are other semantic concepts, though voxels tend to be selective for only one relation or another.

Published today in Nature Neuroscience, our research reveals 2-month-old infants already possess complex visual representations in VVC that align with DNNs.

Human visual cortex representations may be much higher-dimensional than earlier work suggested, but are these higher dimensions of cortical activity actually relevant to behavior? Our new paper tackles this by studying how different people experience the same movies. 🧵 www.cell.com/current-biol...

🚨 New paper out in Science Advances 🚨
With @suryagayet.bsky.social and @peelen.bsky.social, in two fMRI studies we investigate mental object rotations that are driven by the scene context, rather than purely by cognitive operations. 🧵 www.science.org/doi/10.1126/...
I have a PhD opening for my #VIDI BrainShorts project 📽️🧠🤖! Are you or do you know an ambitious, recent (or almost) MSc graduate with a background in NeuroAI and interest in large-scale data collection and video perception? Check out our vacancy! (deadline Feb 15).

Why you shouldn’t trust data collected on Mturk (anymore):
link.springer.com/article/10.3...
While this work highlights problems with Mturk, it also depends on the task & filtering.
That said, we have also migrated to @cloudresearch.bsky.social Connect for data quality like in the good old days!
Now in press at Nature Communications!

Check it out if you are interested in category selectivity, the organization of visual cortex, and topographic models!
A teaser figure showing the process of metamers rendered differentially (MRD). Target scene parameters are used to render a target scene. A new scene is initialized from some starting point, and renders are created from this scene. The loss between the initial and target scenes is measured. MRD allows the gradients wrt the loss to be propagated to the scene parameters (e.g. lighting, geometry or material) for gradient-based optimization.
Legit super excited about this work coming out. My amazing doctoral student @ben.graphics has been working on an idea to use physically based differentiable rendering (PBDR) to probe visual understanding. Here, we generate physically-grounded metamers for vision models. 1/4

🚨 🆕 Preprint 🚨
How does the brain represent natural images?
Using MEG + multivariate analysis, we disentangle contributions of retinotopy, spatial frequency, shape, and texture
Together, our results reveal how visual features jointly and dynamically support human object recognition.

Very thoughtful thread on why it matters to compute the right noise ceiling & why communication is so important to prevent this issue from spreading. Kudos to Sam for being so transparent!
In brief:
NC for best R^2 == data reliability expressed as r
NC for best r == sqrt(reliability)
We recently stumbled upon a surprisingly common misunderstanding in computing noise ceilings that can be quite consequential. So if you care about noise ceilings, please check out Sander’s thread and our preprint! 👇

New preprint w/ Malin Styrnal & @martinhebart.bsky.social
Have you ever computed noise ceilings to understand how well a model performs? We wrote a clarifying note on a subtle and common misapplication that can make models appear quite a lot better than they are.

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.

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

(3) The community can now start to apply Fernanda's tool retrospectively to countless existing anatomical scans to investigate how individual differences in retinotopic organization relate to measures of individual differences in function.
Really curious to hear how the community receives this!
(2) From a more practical point of view, depending on the goal of a study and the required fidelity, we can now confidently say that we may no longer need to collect retinotopic mapping data, freeing up scan time for other tasks. 3/4
01.12.2025 13:51 — 👍 2 🔁 0 💬 1 📌 0(1) If we can accurately predict individual-specific function from structure alone, this highlights that brain structure can act as a strong constraint to brain function in normally-developing individuals. To me, this offers a new paradigm for studying how structure and function are related. 2/4
