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

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.

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, youβll be surprised!

#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?

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.

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?
