- Do direction and orientation preferences form maps in the mouse superior colliculus (SC)? We examined how motion and orientation tuning are organized in SC neurons and their retinal inputs—and how the retinal topography is transformed by collicular circuits. tinyurl.com/mr2zt5rm 🧵👇
- Adam Kampff prioritized spreading knowledge over publishing flashy papers in prestigious journals, but colleagues say his mark on neuroscience was undeniable. The researcher and educator passed away on 9 December. By Lauren Schneider www.thetransmitter.org/systems-neur...

- Can’t wait for Cosyne to continue the tradition of returning reviews on Christmas Eve. Nothing jollier than the anger of a Cosyne reviewer with your mince pie.

- Bichan Wu (@bichanw.bsky.social) & I wrote a tutorial paper on Reduced Rank Regression (RRR) — the statistical method underlying "communication subspaces" from Semedo et al 2019 — aimed at neuroscientists. arxiv.org/abs/2512.12467
- Very excited about this new work from the omnipotent Owen, with me and Ashok Litwin-Kumar! Can we reconcile low- and high-dimensional activity in neural circuits by recognizing that these circuits ~multitask~? (Plausibly, yes 😊)

- I'm more and more convinced that low-dimensional manifolds in the brain are just an artifact of the experimental designs and analyses we use... 🧠📈 🧪
- Dimensionality reduction may be the wrong approach to understanding neural representations. Our new paper shows that across human visual cortex, dimensionality is unbounded and scales with dataset size—we show this across nearly four orders of magnitude. journals.plos.org/ploscompbiol...

- This paper by Ken's group seems like a very important follow up to Stringer + Pachitariu et al (consistent a MSc in the lab found that UMAP could capture their data well): "High-dimensional neuronal activity from low-dimensional latent dynamics: a solvable model" www.biorxiv.org/content/10.1...
