Parietal cortex is causally required for state-dependent decisions

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

In a future where the rich kids are being raised with a digital Cyrano beside them to sweet-talk their way into the best jobs, four friends train together for a battle to prove that other kinds of minds might still have the edge. My new story “Understudies” in Clarkesworld.

New preprint! How can you remember an image you saw once, even after seeing thousands of them? We find a role for humble mid-level visual cortex in high-capacity, one-shot learning. doi.org/10.1101/2025.09.22.677855 🧵🧪1/

Super cool work!

Great article - I remember reading in Newton's biography that he stuck a blunt-end knitting needle between his eyeball and the bone so he could press the back of his eyeball and see colours. He clearly didn't have any students at that point in his career 🙂

I wrote a post about how cool it is that scientists in the 1800s figured out that our color vision must arise from three types of cells just using clever behavioral experiments (a century before we recorded from the cones in the eye!) adiatelic.substack.com/p/history-of... #neuroskyence #SciComm 🧪

The rod:cone ratio in mice is 33:1, in humans (outside the foveola) is 15:1, but is 1:7 in the 13-lined ground squirrel (13LGS). How is this dramatic shift in the rod:cone ratio achieved?/2

Ooh great paper! Wonder why (rat) mPFC here doesn't contain irrelevant stimulus info ('early selection') but (monkey) PFC in the Mante-Sussillo style task has both ('late selection'). Reminds me of this reply by Flesch et al, discussing differences in irrelevant stimulus info in fMRI vs monkey PFC.

Awesome work from the Runyan lab!

Inspired by @sciencehomecoming.bsky.social, I wrote an opinion piece about the importance of science funding in my education for my hometown newspaper. www.bakersfield.com/opinion/comm...

Super proud of this work and as I finish up my #PhD studies I am actively looking for a #postdoc position. I am interested in studying learning and value-based decision making and how cortical and subcortical areas contribute to complex behavior tinyurl.com/LesionsOfM1 #neuroskyence

Really proud and excited to share the final version of our paper, co-led by the Bluesky-less Munib Hasnain!! We asked whether cognitive and motor neural dynamics can be isolated from one another, or whether they’re driven by common neural mechanisms 1/n www.nature.com/articles/s41...

Just finished 'Playing with Reality' by @kellybclancy.bsky.social. Loved it! I picked it up because I thought it was about the history of games, which it is... but it's also so much more than that. Touches upon game theory, minimax, RL, economics, auctions, evolution, Simcity, and more.

It's finally out! Visual experience orthogonalizes visual cortical responses Training in a visual task changes V1 tuning curves in odd ways. This effect is explained by a simple convex transformation. It orthogonalizes the population, making it easier to decode. 10.1016/j.celrep.2025.115235

I knew there had to be someone making beautiful neuroscience videos! youtu.be/9qOaII_PzGY

Awesome new paper from our groups led by the amazing Dr. Emily Oby!
