A new study from Anthropic finds that gains in coding efficiency when relying on AI assistance did did not meet statistical significance; AI use noticeably degraded programmers’ understanding of what they were doing. Incredible.

What happens when a neuroscientist realizes trauma rewired their own brain? ❤️‍🩹

I’ll be sharing that very personal story - the intersection of my research, insights it's brought me & the healing journey I've embarked on - LIVE & LIVESTREAMING on 1/26!

Cosyne workshop list is out! Excited to be presenting one with Josh Siegle on "Bridging the gap between cell types and spike trains" more info on this later!

Thank you! Yes of course we will be sharing it. We should be uploading the preprint in February and you can shoot my PI an email after that but feel free to DM for more info. There’s about 4,000 more units in a different task as well if you only care about high-level spiking properties.

We have a very soon forthcoming preprint on recordings of around 8,000 units from anterior to posterior DLPFC and PMd in a single task! And these are units recorded using unique insertions with laminar probes vs Utah arrays. Fairly precise localization using a chamber grid but not histological.

CMU Offers New Master's in Neural Technologies

The Master of Science in Neural Technologies (MiNT) – jointly offered by CMU's Neuroscience Institute and the Department of Biomedical Engineering — places students at the edge of a fast-moving field where neuroscience meets engineering and AI.

I’ve figured out that these studies were conducted in May of 2025 with Sonnet 3.5/3.7. Back in those days, AI wasn’t very useful at all and took a lot of work to code review because it didn’t follow instructions well or hallucinated. Opus 4.5 is a completely different beast.

It’s just so weird to read this because if you talk to any devs that use these tools, you get near unmitigated praise. I get 5x or more speed ups: ported my entire codebase into Python and built an app in 4 hours with Claude code. I’m convinced people who write this off just don’t know how to use it

Dynamic engagement of the motor cortex in controlling movement Neural circuits do not contribute equally or continuously to behavior. In mice, the motor cortex can be essential or dispensable for movement in different contexts, but how it is dynamically recruited...

Very excited to share a new preprint - my first paper in the @mikeeconomo.bsky.social lab where we asked when and why the motor cortex is recruited for movement control:🧠👇https://www.biorxiv.org/content/10.64898/2026.01.13.699314v1

Anyone else going to #Cosyne2026 and interested in some sport climbing/bouldering? I’m bringing gear for potentially the 11th, 15th, and 18th. Farol da Guia and Sintra.

✨New Corder Lab preprint 🧠⚡️
- from Dr Sophie Rogers !

Differential modulation of aversive signaling by expectation across the cingulate cortex

We image the same ACC + RSC neurons over time during noxious fear learning to ask: who encodes aversion vs who predicts it 🔮

We are excited to announce the 2026 GRC Neurobiology of Cognition (7/19-24) in beautiful Waterville Valley, NH! Registration/abstract submission open. Wonderful speakers/program covering cognition across scales & species, incl. AI & neuromodulation! @desrocherslab.bsky.social @erinlrich.bsky.social

Just finished this thrilling, vulnerable, and inspiring book on friendship, loss, addiction, resilience, and editing memories by Prof Steve Ramirez. Neuroscientists and neuroscience enthusiasts should enjoy this one.

Good thing my workshop got in 🇵🇹🔒

I got both an 8 and a 3 lmao

Same work accepted at Nature Comms but rejected at Cosyne in the same week! Science is so capricious!

My alma mater! Coincidentally, it was also a talk at Puget Sound by an Allen Institute scientist that led me to work there after graduation which then set me on my current path in neuroscience. Very full circle to see students being shown calcium imaging data, some of which I helped collect!

How very American of me! I forgot Europe was a thing!

Cut to me aura farming at the department holiday party having already been accepted for a workshop while everyone else is stressing over abstracts.

Last year was Dec. 23. Previous years were Jan. 21 and 22.

A dynamic spatiotemporal normalization model captures perceptual and neural effects of spatial and temporal context The effects of spatial and temporal context on sensory systems have mostly been studied independently of each other. This study shows that the modulation of visual perception and neural activity by th...

Happy to share this new paper from the lab led by Angus Chapman, now out in PLoS Biology! It presents an integrated spatiotemporal normalization model for continuous vision. @afchapman.bsky.social

Another good work showing not everything and not everywhere! Reminds me of Lin et al which also showed OFC signals reward but does not accumulate it, DLPFC does.

For all #electrophysiology folks!

We just released and end-to-end spike sorting pipeline for large scale ephys!

It's based on Nextflow and SpikeInterface, fully reproducible and parallelized.

Search Jobs - University Affairs

Great news! We are looking for an NHP neuroscientist as the assistant professor level. We have no preconceived ideas -- looking for the most exciting research going. If you have any questions, please reach out. universityaffairs.ca/search-jobs/...

Your perspective is shared and I’ll make sure it’s represented!

There may or may not be a workshop at COSYNE examining “from cell types to spike trains” organized by someone in NHP optotagging/identification and someone from the Allen leading their ephys. Hypothetically, they’d probably love to hear your ideas if you’re there!
