PhD Student in Vision Science at JLU Giessen. Interested in the brain's cartography of the world, as well as our cartography of the brain 👀🗺️
- Reposted by Robert SatzgerThis 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!
- Would love to hear expert views on this paper. It appears to show that the operationalization of brain activity the field has relied on for 3 decades—the BOLD response—is not actually a sensible measure of brain activity. www.nature.com/articles/s41...
- Reposted by Robert SatzgerNew 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. osf.io/preprints/ps...
- Reposted by Robert SatzgerInvestigating 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
- Reposted by Robert SatzgerNew 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.

Gary Zhang's old NIfTI plugin. PRs welcome! Download and build with Xcode: github.com/pmolfese/NIf... #mri #macOS #nifti #neuroscience #science
- Reposted by Robert Satzger1 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...
- Reposted by Robert SatzgerExcited 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! www.nature.com/articles/s43...
- Reposted by Robert Satzger#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!
- Reposted by Robert SatzgerRetinotopic 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.
- Reposted by Robert SatzgerWhat 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. 🧵 ↓ 1/n

- Reposted by Robert SatzgerEva 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! 🧠📈 #NeuroAI 🧪
- How can we make progress in developing a general model of neural computation rather than a series of disjointed models tied to specific experimental circumstances, ask Eva Dyer and @tyrellturing.bsky.social in the latest entry in our NeuroAI series. www.thetransmitter.org/neuroai/acce...
- Reposted by Robert SatzgerPeople 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. www.pnas.org/doi/10.1073/...

- 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?
