Excited to share our preprint! w/@martin_hebart

To understand how primates visually process objects in the world, we rely on both research in human and macaque IT. But what representations of object space are actually shared between them?

We are excited to open the re:vision initiative, a community-driven initiative for replicating and generalizing findings in visual neuroscience, based on the LAION-fMRI dataset.

Why this initiative and why would you want to participate? 🧵

[Martin Hebart @martin_hebart]

I'm proud we are releasing LAION-fMRI, a densely sampled 7T fMRI dataset of natural images, with very broad stimulus sampling for testing countless hypotheses & deeply exploring brain representations. It is now available at

What does LAION-fMRI offer? 🧵

New preprint w/ Malin Styrnal & @martin_hebart

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.

What if you could predict brain function from structure in normally developing individuals?

In her new work, Fernanda Ribeiro (not on X) provides a toolbox that accurately predicts retinotopy from T1 scans alone!

This is exciting for several reasons:

[Lenny van Dyck @levandyck]

How is high-level visual cortex organized?

In a new preprint with @martin_hebart & @KathaDobs, we show that category-selective areas encode a rich, multidimensional feature space 🌈

Programming is essential for modern research in neuroscience and psychology. This Primer introduces ten principles guiding researchers toward writing clear, adaptable, and easily shareable code, ultimately supporting reproducible science.

We make about 3-4 fast eye movements a second, yet our world appears stable. How is this possible? In a preprint led by @LucaKammer we test the intriguing idea that anticipatory signals in the fovea may explain visual stability.

@rgilman33 What’s the visualization tool called?

[Oliver Contier @OliverContier]

Hugely excited that this work with @martin_hebart and @Chris_I_Baker is now out in @NatureHumBehav !!!

By moving from a category-focused to a behaviour-focused model, we identified behaviourally relevant object information throughout visual cortex.

What makes humans similar or different to AI? In a new study, led by @florianmahner and @lukas_mut and w/ @umuguc, we took a deep look at the factors underlying their representational alignment, with surprising results. https://t.co/w1YNZhS6ZW 🧵

If you are interested in the functional neuroanatomy of the visual system, please come by Josefine Zerbe’s and @MaggieMaeWokeUp’s poster on a dataset of densely sampled retinotopy plus 0.8mm DTI from a Connectom MRI that promises a detailed picture of the human visual connectome.

I'm soon going to be looking for a senior postdoc to join my lab who is interested in transitioning to independence and in building their own group, with a strong background in vision science, cognitive computational neuroscience or visual neuroscience. Please RT 1/3

[Martin Hebart @martin_hebart]

ML people: Do you know of any easy way of classifying whether an image is a photograph? For example, telling whether it has a cropped background (vs. e.g. a sky in a photograph), whether half of the image is actually text on top of the image, or whether it is just a diagram?

[Oliver Contier @OliverContier]

How does our brain enable us to make sense of our visual world? 🗺👀🧠

Excited to share our latest work with @Chris_I_Baker and @martin_hebart : “Distributed representations of behaviorally relevant object dimensions in the human visual system”
