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

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.

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.

Really excited to see this preprint out! Fernanda did an amazing job at demonstrating how you can accurately predict retinotopy from T1w scans alone. This is important for several reasons: 1/4

Really amazing work 🤩
New today in @Nature: your visual cortex contains touch-based body maps. bit.ly/VisualBodyMaps
Your brain transforms what you see into first-person, body-referenced codes: A previously unknown bridge between vision and touch.

Why science cannot be this fun always? 😂
‘These results speak for themselves. However, in this digital age many scientists cannot believe results without inferential statistics. We therefore compared for each of the six stimulus locations …’ love that 😂

This has been in the works for over a decade when we were just goofing around testing sound localisation in my in-laws' kitchen... But we finally managed to do some reasonably controlled experiments on this. #psychscisky #neuroskyence

In this preprint, we concurrently fit the HRF alongside pRF parameters doi.org/10.1101/2025...
- HRF varies between visual areas
- HRF also varies with pRF stimulus designs (due to nonlinearities?)
- Esp. when fitting complex models this can skew results a lot!

A nice shift in perceived colour between central and peripheral vision. The fixated disc looks purple while the others look blue.
The effect presumably comes from the absence of S-cones in the fovea.

To predict the behaviour of a primate, would you rather base your guess on a closely related species or one with a similar brain shape? We looked at brains & behaviours of 70 species, you’ll be surprised!
