NSF's #GFRP has been embroiled in controversy over the past year. The agency released FAQs today in response to concerns that applicants have had proposals returned without review (RWR). It says there were about the same number of RWRs this year, but that comparison comes with a big asterisk.

Two-photon calcium imaging at 24,000 lines/s, with the resonant axis spanning 4x what other systems can do. Inertia-free. Diffraction-limited. No tradeoffs. Che-Hang Yu developed a 4x angle multiplier for laser scanning. His paper is out today: opg.optica.org/optica/fullt... 1/n #fluorescenceFriday

I've heard rumors about this video with the flying rat for years. It's just as good as I imagined.

Do Great Apes Know Each Other's Names? Probing Great Ape Comprehension of Social Vocal Labels — Animal Behavior and Cognition

New article out exploring great ape name recognition! We find partial evidence that zoo-living chimps & bonobos know each other's names 👀 Huge thanks to Animal Behavior and Cognition (a great open-access journal) & co-authors for your collaboration!🎉🐵

Happy belated publication of some of my PhD work!

Building on our findings that grid field firing rate changes can cause hippocampal remapping and memory impairment, here we show that this effect has a fixed input-output relationship, and we can even predict how place cells will remap!

hi all - happy to present new work from my laboratory now published in Current Biology - posterior parietal cortex is home to different sub-populations mapping action series versus cross-path structural similarities - congrats to alex johnson and emily xu!

Awesome work by Tudor. This is a fun story that started with a fairly unsurprising observation - that motor cortical activity dissipates rapidly after a CPG-driven movement is initiated. The explanation for why is quite surprising though and begets a bunch of interesting new questions.

AOC: This has now become what we feared most about ICE for a long time—that it would be used as an anti-civilian force with no accountability. At the end of the day, what we saw today was a murder, and murders in cold blood need to be prosecuted.

BBC is reporting that the same ICE officer who murdered Renee Good was involved in another violent incident in June.

Neuronal code for extended time in the hippocampus - PubMed The time when an event occurs can become part of autobiographical memories. In brain structures that support such memories, a neural code should exist that represents when or how long ago events occurred. Here we describe a neuronal coding mechanism in hippocampus that can be used to represent the r …

Any other UC folks encountering extensive red tape when purchasing from IMEC? UCSB says a clause in the purchase agreement requires a special exception from UCOP - is that the case for others? It's been almost 2.5 months since we began an order for more probes and we are still stuck at the uni...

A frontal motor circuit for economic decisions and actions Flexible behaviour requires transforming abstract cognitive representations, such as value preferences, into concrete motor actions. During economic decision-making, individuals evaluate options to gu...

New preprint from the lab!
A frontal motor circuit for economic decisions and actions:
www.biorxiv.org/content/10.6...

We use a novel task in mice, cortex-wide imaging and optogenetics, NPX recording and modelling to reveal a circuit mechanism that transforms abstract decisions to spatial actions.

Lazy but I can't find it and am sure it exists - can someone point me to a paper showing representational drift in *freely moving* animals where *parietal cortex hasn't been sucked out?*

Drosophila maintain a consistent navigational goal angle for days to weeks https://www.biorxiv.org/content/10.64898/2025.12.09.693277v1

Keinath lab already absolutely killing it (as expected)

Environmental representations in mouse hippocampal CA1 reflect the predictive structure of navigation Predictive theories of cognitive mapping propose that these representations encode the predictive relationships among contents as experienced by the n…

Another new paper from the lab: Predictive theories like the SR imply that navigators who navigate differently should have cognitive maps which differ in predictable ways. Here we show that this holds in mouse hippocampal CA1.

#NeurIPS2025

Had a really nice visit to UCSB, learning about the awesome neuroscience research there and presenting our work on voltage imaging in the molecular cellular and developmental biology seminar series.

Thanks to my host Ikuko Smith, who might have the best office view in all of UC!

Also on Sunday Dec 7th, join us for the @neurreps.bsky.social workshop in Upper Level Ballroom 6A.

Arrived #NeurIPS2025 ☀️

If you're interested in the interplay of Geometry, Topology, Algebra w/ Neuroscience & AI, I'll give 2 talks on Sunday:

🌐11:30am: The Algebra of Spatial Navigation (Groups & grid cells)

🍩1:30pm: Topological Deep Learning (Complexes & Graphs)

Large-scale ephys is exploding but spike sorting remains the computational bottleneck. A 2-hr, 6-probe Neuropixels 2.0 Quad Base session can take over a week to sort on a single machine. Here's a better solution. 🧵
