We’re excited to share BrainWideBench, a new benchmark for evaluating how models of neural activity generalize across animals and tasks! 📄 Check out the paper here! arxiv.org/abs/2609.22064 Special shoutout to @alx-adr.bsky.social, who contributed equally as co-first authors!

Hi friends & colleagues! I’m on the hunt for a tenure-track home! I’m a BRAIN Initiative K99/R00 scholar studying learning & memory at the intersection of experimental neuroscience, theory, & machine learning/AI. I’d love to connect & would appreciate help spreading the word! web.mit.edu/hsw/www/

After a long journey through review, our paper is finally out in Nature Communications. We started with a simple problem: The visual cortex is strongly modulated by movement. So how can it represent the visual world without movement interfering with everything? www.nature.com/articles/s41...

We had a great seminar today at RU with @ginapoe.bsky.social Very compelling and interesting argument that REM sleep is important for memory consolidation (btw no ripples during REM) Also super cool hypothesis on heterosynaptic plasticity during different brain states

In mice, hibernation causes the loss of more than 50% of all hippocampal synapses. But after recovery, memories are preserved and most of the 'lost' synapses grow back! www.science.org/doi/10.1126/... "Somehow, the synapse returned."

We released gcpca on CRAN for R users working with high-dimensional experimental data. gcPCA identifies low-dimensional patterns enriched in one condition relative to another, without tuning hyperparameters. 🧠 📈 Package, tutorials, and examples are available here: eliezyer.github.io/gcpca/

Just watched the new Knives Out and I think it's really important you know that the scene in the Seminary's Gym is filmed in the same place Rick Astley filmed the music video for Never Gonna Give You Up. I saw the window tracery and immediately made my friends pause the film so I could tell them.

This looks super interesting! biorxiv server is down for me, but I'm interested to know how these written in stone sequences play back during behavior/task. The first thing that comes to mind is George Dragoi's ideas of pre-play and pre-established neural grammar (in hippocampus).

This 2017 preprint by @suryaganguli.bsky.social is foundational: the dimension of a neural code can't be > that of the experiment used to measure it. Yet it is not very widely known. Maybe because people don't like the message? And because it's "unpublished"? (After writing it, Gao left for SpaceX)
