This paper had a pretty shocking headline result (40% of voxels!), so I dug into it, and I think it is wrong. Essentially: they compare two noisy measures and find that about 40% of voxels have different sign between the two. I think this is just noise!

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.

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 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.

Releasing a NIfTI Quick Look tool compatible with macOS 15+. This is necessary since Apple significantly changed those frameworks and broke the (legendary?) Gary Zhang's old NIfTI plugin. PRs welcome! Download and build with Xcode: github.com/pmolfese/NIf... #mri #macOS #nifti #neuroscience #science

Brain Surfaces of 70 primate species

Brain Surfaces of 70 primate species

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!

🧡Thread on our new preprint with @r3rt0.bsky.social , doi.org/10.1101/2025...

Advancing neural decoding with deep learning - Nature Computational Science A recent study introduces a neural code conversion method that aligns brain activity across individuals without shared stimuli, using deep neural network-derived features to match stimulus content.

Excited to share our News&Views on Kamitani Lab's NatComputSci paper! Their neural code converter enables transformation of brain activity patterns across individuals, and it doesn't need shared stimuli or connectivity information!

#OHBM2025 is around the corner, and I will be there to share the latest development on deepRetinotopy, our toolkit for predicting retinotopic maps from brain anatomy! Please come by poster #1531 on Friday and Saturday!

Retinotopic mapping Fans
Just finished my poster for OHBM. The results blow the discussion about V2 & V3 layout wide open. We find hemispheric asymmetry!
Fantastic work by my student Ruby Barahona, collaboration with the also fantastic @felenitaribeiro.bsky.social and Noah Benson.

What shapes the topography of high-level visual cortex?

Excited to share a new pre-print addressing this question with connectivity-constrained interactive topographic networks, titled "Retinotopic scaffolding of high-level vision", w/ Marlene Behrmann & David Plaut.

If you have not read the story of how Neuromatch came to be, it really is inspiring. We have so many incredible founders and contributors to thank. ❀️

Can't believe it's been five years!

Eva Dyer and I wrote an opinion piece for @thetransmitter.bsky.social on why neuroscience needs to embrace complexity and accept the "bitter lesson" by using a data-driven regime at scale.

With commentary from several wonderful researchers!

People talk a lot about objects, but what about the softness of a cushion, the greenness of an emerald, or the viscosity of oil? In our work just published @pnas.org, we shed light on how we make sense of the hundreds of materials around us.

Very interesting read on the idea of connectomics - to what extent can a static, structural map help us understand function? How limiting is its lack of connection weights?
